Make it a choice menu which offers the 3 C libraries we know about: glibc,
uClibc and musl. While at it, make it possible for the external toolchain libc
to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages
to conditionally include specific CFLAGS (e.g: iproute2).
Because USE_GLIBC et al. can now be selected by external toolchains, we need to
restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN.
While at it, make musl the default C library for external toolchain to match
the internal toolchain.

Configurations without shadow passwords have been broken since the removal
of telnet: as the default entry in /etc/passwd is not empty (but rather
unset), there will be no way to log onto such a system by default. As
disabling shadow passwords is not useful anyways, remove this configuration
option.
The config symbol is kept (for a while), as packages from feeds depend on
it.

Even though ARC tools were released as arc-2016.03
we have a little bit different version name for GDB.
That's because both Binutils and GDB come from the same
git repo but from different branches (and so different tags).

ARC GNU tools of version arc-2016.03 bring some quite significant

This is required to build net-snmp.
If that options is disabled in uClibc then net-snmp doesn't
detect sighold support on its configuration stage and so
defines HAVE_SIGHOLD as 0. That in its turn causes compilation of
the following branch of timerPause() in apps/snmpnetstat:
------------------>8----------------
int oldmask;
oldmask = sigblock(sigmask(SIGALRM));
if (!signalled) {
sigpause(0);
}
sigsetmask(oldmask);
------------------>8----------------
Now in uClibc all 3 sigblock(), sigmask() and sigsetmask()
were removed back in 2005, see:
https://git.busybox.net/uClibc/commit/?id=5aa7aa7fa7ec2a0fe567ac0b2595b46add6f3594
And all that causes net-snmp linkage to fail this way:
------------------>8----------------
.libs/if.o: In function `intpr':
if.c:(.text+0x908): undefined reference to `sigmask'
if.c:(.text+0x90e): undefined reference to `sigblock'
if.c:(.text+0x924): undefined reference to `sigsetmask'
------------------>8----------------
If we enable UCLIBC_HAS_OBSOLETE_BSD_SIGNAL in uClibc then
branch with sighold is used in timerPause() and everything builds as
expected.

This change adds support of ARC ISAv2 processors in
OpenWRT toolchain.
In general gcc for ARC may compile code for both ISA versions
simultaneously but libgcc will be built only for default
architecture that's why it's necessary to specify --with-cpu
on gcc configuration.
As for uClibc we need to use different configurations for
different ARC ISAs.

GCC and Clang are able to check the format arguments given to a
function and warn the user if there is a error in the format arguments
or if there is a potential uncontrolled format string security problem
in the code. GCC does this automatically for some functions like
printf(), but it is also possible to annotate other functions in a way
that it will check them too. This feature is used by glibc for many
functions. This patch adds the attribute to the some functions of musl
expect for these functions where gcc automatically adds it.
GCC automatically adds checks for these functions: printf, fprintf,
sprintf, scanf, fscanf, sscanf, strftime, vprintf, vfprintf and
vsprintf.
The documentation from gcc is here:

uClibc-ng is a spin-off of original uClibc, see http://www.uclibc-ng.org/
We try to regularly add changes from uClibc to uClibc-ng.
We even sent patches and bug reports to the uClibc mailing list.
The config file is compatible between uClibc-ng 1.0 and uClibc git master.
This might change in the future.
Our main goal is to provide regularly a stable and tested release
to make embedded system developers happy.
The main advantage of uClibc-ng over olde good uClibc is regular releases
so there's no need to keep tons of patches on top of years old
