What I think you need to do is
For the first compiler:
--enable-as-accelerator-for=x86_64-pc-linux-gnu

No --enable-accelerator options at all. This should work, if it
doesn't let me know what you find in /somewhere after installation
for both compilers.
It doesn't work without --enable-accelerator:
--enable-as-accelerator-for requires --enable-accelerator
make[1]: *** [configure-gcc] Error 1
Sorry for the delayed reply, I was travelling. There seem to be some
thinkos in the configure script and Makefile; can you try the following
(don't forget to regenerate configure)? It seems to work for ptx (with
some additional changes to allow ptx builds without --enable-accelerator).
