Face some linker errors recently

Face some linker errors recently

[Andreas Müller]

Hi,

to test my patches, I moved my layers from sumo to recent master and
see similar linker (=gold) errors in different recipes. Up to now
there are:

OK I could add

LDFLAGS_append = " -Wl,--no-fatal-warnings"

but that just works around. Does anybody have an idea what's going
wrong with these recipes?

Cheers
