Joseph Myers 93ae1ebaa6 Clean up gnu/lib-names.h generation (bug 14171).
This patch eliminates the mixture of SONAME information in
shlib-versions files and SONAME information used to generate
gnu/lib-names.h in makefiles, with the information in the makefiles
being removed so all this information comes from the shlib-versions
files.

So that gnu/lib-names.h supports multiple ABIs, it is changed to be
generated on the same basis as gnu/stubs.h: when there are multiple
ABIs, gnu/lib-names.h is a wrapper header (the same header installed
whatever ABI is being built) and separate headers such as
gnu/lib-names-64.h contain the substantive contents (only one such
header being installed by any glibc build).

The rules for building gnu/lib-names.h were moved from Makeconfig to
Makerules because they need to come after sysdeps makefiles are
included (now that "ifndef abi-variants" is a toplevel conditional on
the rules rather than $(abi-variants) being evaluated later inside the
commands for a rule).

Tested for x86_64 and x86 that the installed shared libraries are
unchanged by this patch, and examined the installed gnu/lib-names*.h
headers by hand.  Also tested the case of a single ABI (where there is
just a single header installed, again like stubs.h) by hacking
abi-variants to empty for x86_64.

	[BZ #14171]
	* Makeconfig [$(build-shared) = yes]
	($(common-objpfx)soversions.mk): Don't handle SONAMEs specified in
	makefiles.

	[$(build-shared) = yes && $(soversions.mk-done) = t &&
	abi-variants] (install-others-nosubdir): Depend on
	$(inst_includedir)/$(lib-names-h-abi).
	[$(build-shared) = yes && $(soversions.mk-done) = t &&
	abi-variants] ($(common-objpfx)gnu/lib-names.h): New rule.
	[$(build-shared) = yes && $(soversions.mk-done) = t]
	($(common-objpfx)$(lib-names-h-abi)): New rule.
	[$(build-shared) = yes && $(soversions.mk-done) = t]
	($(common-objpfx)$(lib-names-stmp-abi)): Likewise.
	[$(build-shared) = yes && $(soversions.mk-done) = t]
	(common-generated): Append $(lib-names-h-abi) and
	$(lib-names-stmp-abi).
