Do not double-read minimal symbols for PE COFF

This changes coffread.c to avoid re-reading minimal symbols when
possible.  This only works when there are no COFF symbols to be read,
but at least for my mingw builds of gdb, this seems to be the case.

Tested using the AdaCore internal test suite on Windows.  I also did
some local builds to ensure that no warnings crept in.
