In the case of functions, big 'T's ;-)

Loosely: Definitions. One thereof. Multiple definitions means you have
to make an executive decision about which lib was intended, and no
definition implies "go download missing package" or "bad config wrong
machine".

nm -A --defined-only `find /lib -name '*.a'` | grep umoddi3

[snip path]/libgcc.a:_umoddi3.o:00000000 b .bss
           /libgcc.a:_umoddi3.o:00000000 d .data
           /libgcc.a:_umoddi3.o:00000000 ? .stab
           /libgcc.a:_umoddi3.o:00000000 ? .stabstr
           /libgcc.a:_umoddi3.o:00000000 t .text
           /libgcc.a:_umoddi3.o:00000000 t ___clz_tab
           /libgcc.a:_umoddi3.o:00000000 t ___gnu_compiled_c
           /libgcc.a:_umoddi3.o:00000100 T ___umoddi3
           /libgcc.a:_umoddi3.o:00000000 t gcc2_compiled

...implies "-lgcc" is missing from the link line. Now you're certainly
on your own because that's automatically done via "specs".
