[Patch] PowerPC: Fix rs6000-gen-builtins with build != host [PR102353]

[Tobias Burnus]

As mentioned in https://gcc.gnu.org/PR102353 and in the patch,
rs6000-gen-builtins was build to be run on "host" – and then linked and
on on "build".

That caused bootstrap fails at link time.

The patch now does the same as Makefile.in for 'gen*', i.e. build under
build/ (using the Makefile.in rule), the linking is already the same as
for 'build/gen%' and for running, it runs it with valgrind if configured
(as gen* do). additionally, I added the exe extension var, in case it is
needed, following the gen* rules.

Tested with a x86_64-gnu-linux (build) → powerpc64le-linux-gnu (host,
target) build.

OK?

Tobias
