Re: linux/x86 to darwin/ppc cross compiler?

I must confess it has been a long time since I built a cross compiler, but
IIRC you have to put the target includes (and libraries) in a directory
like $prefix/<arch>/{include,lib}
such as /usr/local/sparc-sun-solaris2.8/include
/usr/local/ppc-Darwin-6.2/include

Then the cross compile build will pick them up from there AND any cross
compiles done later will also. Same for production cross links.
