This will make other things blow chunks, such as crt0.  If you're invoking
"ld" directly, the correct solution is "don't do that" (or at least tell us
why you are doing that 8-).

But in any case....

First verify that you can do "cc -v -shared -o libfoo.so ... -lc" without
blowking chunks.  Save the -c output, if it works, because you'll need to
compare it to the below.

Then try removing the %{!shared:...} wrapper around -lc in LIB_SPEC and see
how the output of "cc -v -shared -o libfoo.so ..." (note no -lc) compares to
the output saved above.  The positioning of -lc in the ld link line may be
of importance here.

: in 3.2, this happened in basic_string template instantiation;

Are you using a shared libstdc++?  (This is important to know, as it may
indicate problems elsewhere, possibly related to crtbeginS/crtendS.)
