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 /usr/lib/gcc/x86_64-pc-linux-gnu/6.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: error: read-only segment has dynamic relocations /var/tmp/notmpfs/portage/www-client/firefox-54.0/work/firefox-54.0/ff/toolkit/library/../../gfx/thebes/Unified_cpp_gfx_thebes1.o:Unified_cpp_gfx_thebes1.cpp:function gfxTextRun::SetSpaceGlyph(gfxFont*, mozilla::gfx::DrawTarget*, unsigned int, unsigned short) [clone .cold.368]: error: undefined reference to 'gfxShapedWord* gfxFont::GetShapedWord<unsigned char>(mozilla::gfx::DrawTarget*, unsigned char const*, unsigned int, unsigned int, mozilla::unicode::Script, bool, int, unsigned int, gfxTextPerfMetrics*)' collect2: error: ld returned 1 exit status Reproducible: Always
