Tested on x86_64-darwin24 with Xcode 16.2. OK for trunk?
thanks

Darwin's linker now warns when duplicate rpaths are presented - which
happens when we emit duplicate '-B' paths. In principle, we should avoid
this in the test- suite, however at present we tend to have duplicates
because different parts of the machinery add them. At some point, it might
be nice to have an "add_option_if_missing" and apply that across the whole
of the test infra. However this is not something for late in stage 4. So
the solution here is to prune the warning - the effect of the duplicate in
the libstdc++ testsuite is not important it will make the exes very slightly
larger but it won't alter the paths that are presented for loading the
runtimes.

* testsuite/lib/prune.exp: Prune XCode ld warning about duplicate
rpaths.
