You can configure the compiler and linker through src/conf-cc and
src/conf-ld, here's an example for the dietlibc

 http://smarden.org/runit/usedietlibc.html

For real cross-compiling, some handwork must be done.  The build system
uses runtime tests to detect support for platform specific features, see
the sysdeps target in src/Makefile.  If it cannot run test programs, you
need to find out and manually choose the appropriate headers.

HTH, Gerrit.
