Alan recently changed the diagnostic in binutils for changing various
attributes of a section from a warning to a hard error.


This caused the FRV port to fail to build frvbegin/frvend because of
differences in the flags for the .ctors/.dtors sections.

This patch twiddles frvbegin.c/frvend.c in libgcc to avoid the error.

I've verified this fixes the libgcc build failure for FRV and verified
that the GCC testresults have returned to normal.

Installed on the trunk,
