I just played with my build-robot script. It now attempts to build
gmp, but that fails:
Making all in mpn

make[2]: *** [add_n.lo] Error 1
add_n.s is linked from some vax directory. Unfortunately, they use old
assembly there which current GAS will not assemble:

40 addl2 $3,r0
When accessing the AP register, the name should be prefixed with '%'.
The assembly function's name had one _ too much in front, as well as
the .type ..., @function was missing.
With this patch to gmp, I can build GCC (build=i686-linux,
host=target=vax-linux-uclibc). It's not yet tested at all, though...
