IIUC, you really want one new port that installs all mips headers. The
gcc/binutils port can be modified for ${ARCH} =3D=3D "mips".
Something like this should work:
http://people.freebsd.org/~flz/local/ports/freebsd-mips.shar
The thing is, it will have to be modified everytime a header is
added/removed. The easy way out is to only support HEAD so you don't
have to use OSVERSION conditionals. The other solution I'm seeing is
to fetch sources from FTP (which is obviously more work).
