configure --help shows

Build-Tools Needed to Compile Temporary Applications for Cross-compiling:
  --with-build-cc=XXX     the build C compiler ($BUILD_CC)
  --with-build-cpp=XXX    the build C preprocessor ($BUILD_CPP)
  --with-build-cflags=XXX the build C compiler-flags
  --with-build-cppflags=XXX the build C preprocessor-flags
  --with-build-ldflags=XXX the build linker-flags
  --with-build-libs=XXX   the build libraries
 
and there's more discussion in INSTALL about the options.

autoconf doesn't really support that.
