Comment (by michaelld):

 Ah yes. "gnm" == "GNU nm". I guess since we're building GCC (and, past the
 bootstrap phase where Clang would be used) it shouldn't be a surprise that
 "gnm" is searched for & used if found LOL. Guessing since this issue is
 during configuration that there's probably a relatively simple patch that
 would fix this configure script
 (`/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc8/libgcc8/work/gcc-8.2.0/libgomp/configure`)
 -- e.g., "don't search for "gnm" , just "nm" ... might be worth exploring,
 since we never want to use MP binutils ...
