[Benjamin Kosnik]

Cross compiling implicitly assumes newlib. If your goal is to build a
compiler for sh-linux on x86-linux that uses specific version of glibc,
you have to have a more elaborate configure command than just
--target=sh-elf.

Cross-linux toolchains are called 'host x host.'

This is what the hacked parts of configure.in are for. 

What are you trying to do, what have you tried, and where did the
documentation fall down?
