On a recent system update, firefox-54 got pulled in and it fails to compile with the following error:

/usr/lib/gcc/x86_64-pc-linux-gnu/6.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: error: /var/tmp/notmpfs/portage/www-client/firefox-54.0/work/firefox-54.0/ff/toolkit/library/../../gfx/thebes/Unified_cpp_gfx_thebes1.o: requires dynamic R_X86_64_PC32 reloc against '_ZN7gfxFont13GetShapedWordIhEEP13gfxShapedWordPN7mozilla3gfx10DrawTargetEPKT_jjNS3_7unicode6ScriptEbijP18gfxTextPerfMetrics' which may overflow at runtime; recompile with -fPIC

Turns out this is a known bug upstream, related to PGO...
https://bugzilla.mozilla.org/show_bug.cgi?id=1332788

Removing the PGO use flag resolved the issue.
