Baruch, All,
On 2017-06-16 06:32 +0300, Baruch Siach spake thusly:
> Since glibc 2.17, executable link command need not include the -lrt option for
> clock_* system calls. As a result, over time less and less software packages
> bother to check whether to toolchain needs -lrt. We are now at a point where
> maintainers refuse to add this complexity into their build system. This
> requires Buildroot to carry patches fixing this issue indefinitely.
>
> glibc 2.17 is now 4.5 years old. There is no reason to use an older version
> with current software.
>
> This commit removes the predefined profile for CodeSourcery sh toolchain that
> is based on glibc 2.16. One may still use the custom external toolchain
> support in Buildroot to get this toolchain back, and deal with any build
> issues that this toolchain causes.
