You need to test if this doesn't break a full bootstrap. A full
bootstrap works like this:
1. You compile a cross binutils and install it.
2. You try to compile a cross gcc, which will fail in libgcc2.a, but
you can force it with -k. The resulting compiler will be in a
half-broken state.
3. Compile and install Mach. We need to be able to at least install
the header file, but the gcc from step 2 should already be able to
compile the full kernel.
4. ...
The thing is that the standard autoconf checks fail and bail out of
configure if they find gcc in the half-broken state above. I think
this is the reason why they were not used.
OTOH, I could just be making it all up :) It is certainly the problem
I am currently seeing in the Hurd on L4, and it seems to make sense
that the same would happen with a gnumach configure based on the
standard checks.
In any case, the above full bootstrap procedure (assuming you cleared
out your /usr/i686-gnu first, or whatever path you use) must work more
or less as described in INSTALL-cross or Alfred's Cross-compiling
guide from last september. If you can't configure and run make
install-headers with a broken gcc, you are in some trouble getting the
system up and running.
