Hi Iain,
We don't want to run dsymutil if there are .o files, let the developer
do that.
If someone just does gcc -g -o foo foo.c, then any debugging information
will be lost when the temporary .o file is removed, thus, to allow
debugging such a foo, the compiler must run dsymutil.
Of course, it doesn't need to run for stabs, or -g0.
Strange, Apple's gcc-4.2 doesn't have this bug (-lm), yet that portion
of the specs appears identical.
