If we enable -fstack-protector while building libunwind, function
__stack_chk_fail_local will be referred to for i386 and powerpc32
arches. This will cause link failure because the default gcc build
specs says no link_ssp if -nostdlib is given.

OpenSSL is built with the generic linux settings for most targets,
including aarch64. These generic settings are designed for 32-bit CPU and
provide no assembler optmization: this is widely suboptimal for aarch64.
This patch simply switches to the aarch64 settings that are already
available in OpenSSL.
Here is the output of "openssl speed" before the optimization, with
"(...)" representing build flags that didn't change:
OpenSSL 1.0.2l 25 May 2017
options:bn(64,32) rc4(ptr,char) des(idx,cisc,2,int) aes(partial) blowfish(ptr)
compiler: aarch64-openwrt-linux-musl-gcc (...)
And after this patch, OpenSSL uses 64 bit mode and assembler optimizations:
OpenSSL 1.0.2l 25 May 2017
options:bn(64,64) rc4(ptr,char) des(idx,cisc,2,int) aes(partial) blowfish(ptr)
compiler: aarch64-openwrt-linux-musl-gcc (...) -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM

For some reason AES and blowfish do not benefit, but SHA performance
improves between 1.7x and 15x. SHA256 clearly benefits the most from the
optimization (4.5x on small blocks, 15x on large blocks!).

Blowfish does not seem to have assembler optimization at all, and SHA
still benefits (between 1.6x and 14.5x) but is generally slower than in
non-EVP mode.
However, AES performance is improved between 5.5x and 27.5x, which is
really impressive! For aes-128-cbc on large blocks, a core i7-6600U
@2.60GHz is only twice as fast...

Hardening is enabled by default in libwolfssl at build-time.
However, the `settings.h` header is exported (along with other headers)

This is to eliminate any ambiguity about the cyassl/wolfssl lib.

Fixed an authentication bypass issue in SSL/TLS. When the TLS
authentication mode was set to 'optional',
mbedtls_ssl_get_verify_result() would incorrectly return 0 when the
peer's X.509 certificate chain had more than
MBEDTLS_X509_MAX_INTERMEDIATE_CA intermediates (default: 8), even when
it was not trusted. This could be triggered remotely on both the client
and server side. (Note, with the authentication mode set by
mbedtls_ssl_conf_authmode()to be 'required' (the default), the handshake
was correctly aborted).

elfutils turns on -Werror by default, and patch 100-musl-compat.patch
changes how strerror_r is used and we no longer use the function's
return value. This causes the following build error/warning to occur

dwfl_error.c: In function 'dwfl_errmsg':

declared with attribute warn_unused_result [-Werror=unused-result]

uClibc doesn't implement strerror_l() and thus libnl starting from

To work-around that problem we'll just do a check on strerror_l()
availability during configuration and if it's not there just fall back
to locale-less strerror().
