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.

since eglibc is deprecated just use glibc as name
- fix build errors w. stack-protector (observed for x86_64):
libresolv_pic.a(gethnamaddr.os): In function `addrsort':
gethnamaddr.c:(.text+0x425): undefined reference to `__stack_chk_guard'
by additionally setting libc_cv_ssp_strong=no
like previously libc_cv_ssp=no was set
- fix compile errors on 2.24 x86 introduced by
upstream changesets "Optimize i386 syscall inlining"
errors are like:
- https://sourceware.org/ml/libc-alpha/2015-10/msg00745.html
and trying to fix with the whats suggested at:
https://patchwork.openembedded.org/patch/118909/
leads to other error:
gcc6: elf/librtld.os: In function `__mmap':

or:
gcc5: elf/dl-load.os
{standard input}: Assembler messages:

instead of testing other flags/effects (-fno-omit-frame-pointer)
just use -O2 (like buildroot does) instead of -Os
boot+pings tested on:
qemu malta (le+be) (gcc5+bin2.25.1)
qemu aarch64 (gcc5+bin2.25.1)

-fno-plt and musl-libc patches already get upstream, then dropped
in GCC 6. Other patches are almost identical compared to GCC 5.4.

Use ./patches and ./patches-arc instead of version dependent patches.
We should have only one main supported version (along with the special

No extra libc header build step is done, so no extra toolchain is needed
for preparing it.
This saves a significant amount of build time and disk space

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).
Also removing an extra patch that made its way into release.

This change switches ARC tools to the most recent arc-2016.03
version.
ARC GNU tools of version arc-2016.03 bring some quite significant
changes like:
* Binutils v2.26+ (upstream commit id 202ac19 with additional ARC
* patches)
* GCC v4.8.5
* GDB 7.10

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.

mips returns -ENOSYS in case it can not handle the vdso call and wants
the libc to call the original syscall in such a case. This fixes the
patch to add such handling. I hope this fixes the random reboots I got.
