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 && $(soversions.mk-done) = t] ($(common-objpfx)gnu/lib-names.h): Remove rule. [$(build-shared) = yes && $(soversions.mk-done) = t] ($(common-objpfx)gnu/lib-names.stmp): Likewise. Split and moved to Makerules. [$(build-shared) = yes && $(soversions.mk-done) = t] (before-compile): Don't append $(common-objpfx)gnu/lib-names.h here. [$(build-shared) = yes && $(soversions.mk-done) = t] (common-generated): Don't append gnu/lib-names.h and gnu/lib-names.stmp here. * Makerules [$(build-shared) = yes && $(soversions.mk-done) = t] (lib-names-h-abi): New variable. [$(build-shared) = yes && $(soversions.mk-done) = t] (lib-names-stmp-abi): Likewise.

[$(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-generated): Append $(lib-names-h-abi) and $(lib-names-stmp-abi). * scripts/lib-names.awk: Do not handle multi being set. * sysdeps/unix/sysv/linux/aarch64/Makefile (abi-lp64-ld-soname): Remove variable.
