[Buildroot] [PATCH 00/14] toolchain-external: remove support for glibc before 2.17

[Baruch Siach <baruch@tkos.co.il>]

As discussed[1] recently on the list it is time to remove support for glibc 
older than 2.17. This does not mean that toolchains with old glibc will stop 
working. It only means that we stop fixing older glibc build issues. In 
particular, the need to link with librt for clock_* system calls.

The only significant user visible change in this series is the removal of 
CodeSourcery toolchains for x86 and sh.

Two patches update a comment section and the manual to take into account the 
removal of toolchain in this series and in previous commits. A few more 
per-package patches remove local patches for the glibc librt issue.

The first patch is an unrelated fix to the external toolchain section in the 
manual.
