libtool: optional filename-based shlib versioning on aix.
Support filename-based shared library versioning on AIX with the
lib.so library filename extension, which is used with runtime
linking only. Runtime linking is enabled by the -brtl linker
flag for executables and the -G linker flag for Shared Objects.
The behaviour is similar to Linux/SVR4 DT_SONAME, hence the name
"aix-soname=svr4".
* Makefile.am (TESTS_ENVIRONMENT): Pass with_aix_soname value
via lt_cv_with_aix_soname into testsuite.
* configure.ac: AC_SUBST with_aix_soname for testsuite.
* libltdl/loaders/dlopen.c (vm_open): Use RTLD_MEMBER flag for
dlopen when the filename does specify an archive member between
"()". Otherways, retry with appending LT_SHARED_LIB_MEMBER when
loading fails without but archive file seems to exist.
* m4/libtool.m4 (dynamic_linker): Describe configured shared
library versioning variant according to with_aix_soname and
runtime linking.
(soname_spec, library_names_spec, shlibpath_overrides_runpath)
(postinstall_cmds, postuninstall_cmds, hardcode_direct)
(hardcode_direct_absolute, no_undefined_flag)
(allow_undefined_flag): Set according to with_aix_soname and
runtime linking configuration.
(export_symbols_cmds): Decorate symbols with the weak keyword.
(archive_expsym_cmds): Create both shared libraries according to
with_aix_soname and runtime linking configuration. Filter -brtl
linker flag from compiler_flags for shared libraries due to its
side effects.
(enable_static): Respect with_aix_soname for disabling as well.
* m4/ltdl.m4 (LT_SHARED_LIB_MEMBER): Define, set based on the
value of the shared_archive_member_spec libtool variable.
* m4/ltoptions.m4 (_LT_WITH_AIX_SONAME): New. Provides
commandline option --with-aix-soname=aix|svr4|both. Declares
$shared_archive_member_spec as libtool variable.
(_LT_SET_OPTIONS): Define LT_INIT options "aix-soname=aix",
"aix-soname=svr4", "aix-soname=both". Default is
"aix-soname=aix".
* doc/libtool.texi (LT_INIT): Document new options.
* tests/deplibs-ident.at: To define whether this test should
XFAIL, use hardcode_action, hardcode_direct,
hardcode_direct_absolute configuration settings instead of
platforms aix, bitrig, hppa-hpux, interix or openbsd.
* tests/versioning.at: When shared_archive_member_spec is defined
and LDFLAGS contain -brtl, we can run the versioning check.
* NEWS: Update.
