toolchain: remove CodeSourcery sh toolchain

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.
