This fails on cygwin due do a comparison error in _chkstk.o.

The cygwin.asm file gets preprocessed.  Since the resulting .s file that actually gets sent 
to the assembler isn't explicitly specified in the makefile fragment, a temporary filename 
gets randomly generated.

The comparison error comes from a difference in the debug name of the randomly 
generated temporary filename.  The objectdumps of both files is the same.

I'm assuming this would happen in a lot of places, so here is a patch to fix the problem by 
eliminating the creation of the temporary files by specifying "-pipe" in LIBGCC2_CFLAGS. 

Restrapped along with Geoff's patch on i686-pc-cygwin.

OK to install?
