Hi,
this patch synchronize handling - and fixes latent bug - of
static/shared flags with cygwin-host.
in static case prior code added to linker-script reference to shared
libgcc, which is obviously wrong.
Due link-order the shared version doesn't get actual linked, but
nevertheless there is a latent issue.
ChangeLog

* config/i386/mingw32.h (SHARED_LIBGCC_SPEC): Synchronize with
cygwin-host.
Tested for i686-w64-mingw32, and x86_64-w64-mingw32. I will apply
tomorrow if there aren't any objections.
Regards,
Kai
