Because autoconf 2.59 gave an error if I didn't change the name.

It looked like the common fix for this was to rename it to
GAS_FOR_TARGET. I see that all these files are shared, I didn't realise
that. I thought that GCC was already configuring everything with 2.59
but I see they still use 2.13 for the toplevel configure and have the
same configure.in (and Makefiles) as the src tree. Oh well.

Yes, I expect so. I guess this last bit will have to wait for a while.
