LFS support for libbacktrace

This fixes the [f]open use in libgfortran.  Doesn't fix the ones
in libsanitizer because those appearantly use a copy because they
need to rename stuff...

Bootstrapped and tested on x86_64-unknown-linux-gnu, ok for trunk
and branches?

Thanks,
Richard.

	* configure.ac: Add AC_SYS_LARGEFILE.
	* config.h.in: Regenerate.
	* configure: Likewise.
