Add CROSS_TARGETS to the list of GASES to build. We end up with a separate

gas for each target format. So for m68k targets that means several
gases. I wanted a m68k gas for VxWorks which uses aout in sun3 big
endian format, cross compiled on i386 under FreeBSD using libraries
supplied by DEC and intended by them for cross compilation on Alpha
under OSF/1. And it actually works!
