[PATCH] GNU/Hurd config update

[Mark Kettenis]

Argh!  Turns out we have been buiding crtbegin.o with -fPIC and
crtbeginS.o without, for quite some time now.  The attached patch
corrects this by making the Hurd share its target-specific make
details with Linux.  We already were sharing the host-specfic details
and it is the intention of the Hurd hackers to follow Linux as closely
as possible.  As an added bonus this enables the shared libgcc stuff
for the Hurd.

Could someone please install this patch?

	* configure.in: Reorganize handling of *-*-gnu*, to share target
	specific make details with Linux.  Update comments to clarify
        the distinction between GNU/Linux and GNU/Hurd.
	* config/t-gnu (LIBGCC1, CROSS_LIBGCC1, CRTSTUFF_T_CFLAGS,
	TARGET_LIBGCC2_CFLAGS): Remove.  We now use the settings from
	config/t-linux for the Hurd.
