make universe errors..

[Julian Elischer]

In testing my MRT changes I noticed several failures that I can't 
really blame my change... (maybe)
for example:

for both amd64 and arm (the architectures that have
completed so far on my build) I see:

/src/lib/libc/string/wmemset.c -o wmemset.So
building shared library libc.so.7
/usr/obj/amd64/usr/src/tmp/usr/lib/libgcc.a: could not read symbols: 
Archive has no index; run ranlib to add one


how many errors in a make universe are expected?

who knows about this stuff?
