toolchain: Rework external toolchain libc selection

2016-09-28T06:39:01+00:00

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.

glibc: add 2.24

2016-08-30T08:51:21+00:00

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':
(.text+0x131a9): undefined reference to `__libc_do_syscall'
or:
gcc5: elf/dl-load.os
{standard input}: Assembler messages:
{standard input}:5129: Error: symbol `__x86.get_pc_thunk.cx' is already defined

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)
qemu x86_64 (gcc6+bin2.26)
qemu x86 generic (gcc6+bin2.26)

toolchain: skip gcc/minimal for musl

2016-07-07T13:13:40+00:00

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
