This patch removes the --enable-oldest-abi configure option, which has
long been bitrotten (as reported in bug 6652). The principle of
removing this option was agreed in the thread starting at
<https://sourceware.org/ml/libc-alpha/2013-07/msg00174.html>.
Tested for x86_64 and x86 that the installed shared libraries other
than libc.so are unchanged by this patch and that libc.so disassembly
and symbol versions are unchanged (debug info changes because of
changed line numbers in csu/version.c).
[BZ #6652]
* Makeconfig (soversions-default-setname): Remove variable.
($(common-objpfx)soversions.i): Don't pass default_setname to
soversions.awk.
* Makerules ($(common-objpfx)abi-versions.h): Don't pass
oldest_abi to abi-versions.awk.
* config.h.in (GLIBC_OLDEST_ABI): Remove macro undefine.
* config.make.in (oldest-abi): Remove variable.
* configure.ac (--enable-oldest-abi): Remove configure option.
* configure: Regenerated.
* csu/version.c (banner) [GLIBC_OLDEST_ABI]: Remove conditional
text.
* scripts/abi-versions.awk: Do not handle oldest_abi variable.
* scripts/soversions.awk: Do not handle default_setname variable.
* sysdeps/mach/hurd/configure.ac: Do not handle oldest_abi
variable.
* sysdeps/mach/hurd/configure: Regenerated.
* sysdeps/unix/sysv/linux/configure.ac: Do not handle oldest_abi
variable.
* sysdeps/unix/sysv/linux/configure: Regenerated.
This patch removes the first column (patterns matching configuration
names) from shlib-versions, leaving shlib-versions entry selection
based purely on sysdeps directories.
An implication of this removal is that the default for any non-Linux
ports using NPTL will be the same SONAMEs for NPTL libraries as for
Linux (as those defaults, previously limited to .*-.*-linux.*, are
left in nptl/shlib-versions and nptl_db/shlib-versions).
Special host_os handling in configure.ac that was purely for
shlib-versions is removed. (The host_os setting is still used for
libc-abis - see
<https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding
that - but no entries there are affected by this change.)
Tested on x86_64 and x86 that the installed shared libraries are
unchanged by this patch.

libidn/ChangeLog:
* shlib-versions: Remove first column with configuration names.
shlib-versions files can contain ABI lines that map triplets to a
canonical ABI name. This name was once used for various purposes
where test baseline files for different ABIs went in a single
directory; now these purposes use sysdeps files, generation of headers
which have per-ABI variants uses abi-variants and related Makefile
variables and the shlib-versions ABI names are unused. This patch
duly removes those lines and associated build system support for them.
Tested for x86_64 (both a full testsuite run and confirming the
installed shared libraries are unchanged by the patch).
* Makeconfig ($(common-objpfx)soversions.mk): Do not generate
abi-name definition.
* scripts/soversions.awk: Do not handle or generate ABI lines.
* shlib-versions: Remove ABI entries.
* sysdeps/powerpc/nofpu/shlib-versions: Remove file.
* sysdeps/x86_64/x32/shlib-versions: Remove ABI entry.

[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.
$(config-sysdirs) for shlib-versions files.
* Makeconfig ($(common-objpfx)soversions.i): Replace shell loop with
use of ...
* scripts/soversions.awk: ... this new file. Collect lib info and
match any DEFAULT line before emitting anything, so DEFAULT can come
later in the concatenation of shlib-versions files.
