Job Bautista 5b438179ad Issue #2079 - Fix linking libxul on *nix when using a linker other than bfd.
Don't mark the .kPStaticModules section as relro for bfd, as the linkers on
 Windows and Mac don't do this anyway.
Add a section insert of .kPStaticModules to config/expandlibs_exec.py, which
 seems to be the primary cause of linking bustage on gold, lld, and mold.
