Actually citing libgcc_s.so in full makes things a bit clearer: $ cat libgcc_s.so /* GNU ld script Use the shared library, but some functions are only in the static library. */ GROUP ( libgcc_s.so.1 -lgcc ) > So I think the desire to save space expressed in > feeds/packages/devel/gcc/README is well-intentioned but possibly stale, > so maybe the following, too? Maybe we should be removing libgcc_pic.a > but not libgcc.a? Seems reasonable. Since gcc seems to work for Christian as is, this might be architecture dependent. Christian, any insight on this? As far as binutils is concerned the patch below seems to work as expected, so I can now add my Signed-off-by: Harald Geyer <har...@ccbib.org> Felix, can you take this as is or should I resend the patch?
