I patched following two files with __attribute__ ((used)) which helped to go
further, having a new issue:
/home/marxin/Programming/firefox/xpcom/components/nsComponentManager.cpp: In
function ‘_ZN22nsComponentManagerImpl23InitializeStaticModulesEv.part.59’:
/home/marxin/Programming/firefox/xpcom/components/nsComponentManager.cpp:275:0:
