[BZ #632]
2005-02-10  Roland McGrath  <roland@redhat.com>
	[BZ #632]
	* scripts/soversions.awk: Expect cpu, vendor, os as separate variables
	from command line.
	Grok shlib-versions lines with WORDSIZE* in second column.
	Add new leading column to output, DEFAULT for existing output lines.
	Also emit lines with WORDSIZE* for alternate configurations.
	* Makeconfig ($(common-objpfx)soversions.i): Pass those variables.
	($(common-objpfx)soversions.mk): Grok new column, use only DEFAULT.
	($(common-objpfx)gnu/lib-names.stmp): Depend on soversions.i instead
	of soversions.mk; replace inline shell script with use of ...
	* scripts/lib-names.awk: New file.  If input has non-DEFAULT lines,
	emit multiple sets of macros under #if.
	* shlib-versions (x86_64-.*-.*): Add WORDSIZE32 line mapping to i686.
	(s390x-.*-.*): Likewise for s390.
	(powerpc64-.*-.*): Likewise for powerpc.
	(sparc64-.*-.*): Likewise for sparc.
