[Committed] Fix for ppc64 libgfortran bootstrap failures

[Steve Kargl]

I've committed the attached patch as a fix for the recent
bootstrap failures on powerpc64 linux due to libgfortran.

Both Revital1 Eres and Diego Novillo tested a version of
the patch that used '#if 0 ... #endif' to remove the 
offending code.  I've also verified with Chris, the author
of the ISO C binding path, that the offending code could
be removed.  It is actually reminants from his implementation
of the Fortran 2003 VALUE attribute, which was supplanted 
by a patch from Paul Thomas.

Although this patch fixes the bootstrap failure, I believe,
and Diego as re-inforced my belief, that the Fortran front-end
may be overwriting memory.  It looks like we (gfortran gang)
are due for some valgrind sessions.

I bootstrapped and regression tested this on i386-*-freebsd
and amd64-*-freebsd.  Revital1 and Diego were able to at
least bootstrap on ppc64 linux.
