The libgomp bootstrap rules are conditional on:
@if target-libgomp-bootstrap
and this is decided in configure without regard to the contents of Makefile.def
.

I have a patch to hack the dependency of libstdc++-v3 on libgomp into
configure.ac .

configure(.ac) uses language fragments, but these are not really appropriate
for dependencies: libgomp belongs to the C language, but it needs to be
bootstrapped when libstdc++-v3 is boostrapped - which may or may not be
the case when the C++ language is enabled.
If someone has some spare time, (s)he can rewrite that
bit of configure machinery to use Makefile.def .
