The usual thing to do is set CC to the compiler, then ignore the fact
that you're
using a crosscompiler.  This usually just works, assuming you're using
a modern build system.

http://www.ailis.de/~k/docs/crosscompiling/
has some notes about how to crosscompile a few common libraries
(along with some outdated notes about how to build a crosscompiler).

You might also look at frameworks that make crosscompiling standard
packages easy, e.g. ptxdist, buildroot, or familiar.
