This patch, relative to a tree with
<https://sourceware.org/ml/libc-alpha/2014-09/msg00114.html> (pending
sparc testing),
<https://sourceware.org/ml/libc-alpha/2014-09/msg00129.html> and
<https://sourceware.org/ml/libc-alpha/2014-09/msg00151.html> (pending
powerpc64 testing) applied, 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.
