Commit f4d9d7a removed support for version specific patches; but it also
broke applying of patches in the patches glibc dir.
Fix the issue by setting PATCH_DIR to $(PATH_PREFIX)/patches similar as
musl/common.mk.

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.

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:

No extra libc header build step is done, so no extra toolchain is needed
for preparing it.
