Fix building packages with LTO when CONFIG_PKG_ASLR_PIE is enabled.
Despite comment of PR lto/80838, it seems that GCC needs -fPIC on linker
command line, even if all objects are -fPIC. This may change as PR
lto/80838 is merged into 8.1

This partly reverts ca32373c95 which lets
profiles that suppress packages to alter the package selection for all
devices of the target when building with CONFIG_TARGET_PER_DEVICE_ROOTFS.
In particular, this caused the brcm47xx Edimax PS-1208MFG profile to
disable mtd, dropbear, firewall and other essential packages for all
brcm47xx/generic builds.
To solve this problem, prevent profiles from mangling the global
DEFAULT_PACKAGES selection and restrict the supression of negated
packages to the local PACKAGE variable list only.
Fixes ca32373c95 ("target.mk: let profile remove from DEFAULT_PACKAGES")

Allow enabling/commenting/disabling each feed individually by using a
tristate config symbol.
Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
Setting CONFIG_FEED_... symbols combined two different effects: Disabling
a feed in the generated opkg distfeeds.conf, and omitting the feed from
PACKAGE_SUBDIRS.
It does not make sense to omit built feeds from PACKAGE_SUBDIRS, as it will
only lead to packages that can be enabled in .config (and that will
consequently be built) not to be found during rootfs creation, breaking
the build. All feeds that packages are emitted to should simply always be
added to PACKAGE_SUBDIRS instead; the CONFIG_FEED_... only configure the
generated distfeeds.conf like this.

A new python script scripts/download.py is added to fetch tarballs using

GitHub imposes a 60 reqs/hour rate limit on unauthenticated API

argument. However, observation indicates that archive download is NOT
subject to this limit at the moment. In the rare cases where download
fails because of this, we will falback to using DownloadMethod/git

Busybox time supports the GNU time '-f' syntax used by the build time
logging implemented in ff6e62b288, however the prerequisite check added
only works with GNU time installed as `time` or `gtime`.
As busybox is a multicall binary, the name of the symlink setup by
SetupHostCommand also must be changed from `gtime` to `time` to fix the
value of argv[0]. This causes a number of shells (including bash) to use
their builtin impelementation of time, so the sole invocation has been
changed to use `env time` to use the value found on the $PATH.

Shorten the version string in Netgear factory image header in order
to enable u-boot TFTP recovery flash mode to work again.
Strip 'r7210-14cb05909a' into 'r7210' in the Netgear image header
by removing the hash (anything after "-").
background:
Some Netgear routers have recently been unable to flash Openwrt
factory image with the TFTP recovery flash mode provided by Netgear
u-boot. That is due to over-long Openwrt version string overflowing
into the router type string in u-boot code. Modern git versions
produce 10-digit short hashes for the Openwrt main repo, and that
causes the version string to be too long in the image header,
breaking the image ID verification by the TFTP flash routine.
(Other option could be to force a shorter hash in scripts/getver.sh,
but as the problem only concerns Netgear routers, let's patch just
them.)

When CONFIG_AUTOREMOVE is enabled, the build system touches an additional
".autoremove" stamp file in the cleaned build directory.
Since the autoremove stamp file is touched after the compile process
completed, it ends up being the most recent file of the package build
directory, causing the timestamp.pl check of depends.mk to erroneously
declare the ".built" and ".prepared" stamp files as stale, triggering
a forced clean-build submake process.
Fix the problem by using the ".built" stamp file as modification time
reference when touching the ".autoremove" stamp file.

The current image build code has a number of race conditions and interface
contract violations in the custom image build steps:
- Build/install-zImage, solely used by at91, relies on $(PROFILE_SANITIZED)
which is not available when building with CONFIG_TARGET_MULTI_PROFILE
- Build/at91-sdcard, which may run concurrently, creates scratch files at
fixed locations and manipulates target files directly which can lead
to file corruption and other unexpected failures
Rename the install-zImage macro to at91-install-zImage and move it to the
at91 image Makefile since this target is the sole user. Also utilize "$@"
as output file name and switch the usage of $(PROFILE_SANITIZED) to
$(DEVICE_NAME) in order to fix naming under multi profile builds.
Fix the at91-sdcard macro to construct scratch file paths relative to "$@",
which is guaranteed to be unique and store the final artifact output in "$@"
as well, instead of inside $(BIN_DIR). The generic image build code takes
care of moving a build steps "$@" output to the final destination in a
concurrency-safe manner.
Finally remove the broken install-zImage from the generic image-commands
Makefile.
