config.gcc (*-*-openbsd*): Add fragment to compile libgcc correctly for shared configurations.

2001-07-13  Marc Espie  <espie@cvs.openbsd.org>

	* config.gcc (*-*-openbsd*):  Add fragment to compile libgcc
	correctly for shared configurations.
	* config/t-libgcc-pic:  New.
	* config/{i386,m68k,sparc}/t-openbsd:  New.
	* config/openbsd.h:  Include cpu_spec in cpp_spec where needed.
	Support -shared.  Support debugging libraries with -g.
	* config/i386/openbsd.h:  Correct ASM_COMMENT_START.  Ensure dwarf2
	frame information does not emit pointer diffs.
	* config/sparc/openbsd.h:  Ensure dwarf2 frame information does not
	emit pointer diffs.
