* doc/invoke.texi: Remove documentation of %M spec.
* gcc.c: Likewise.
(init_spec): Remove %M suffix from -lgcc_s.
(do_spec_1): Remove 'M' case.
* mklibgcc.in: Remove SHLIB_MULTILIB handling. Expect SHLIB_LINK
to put shared libraries in the multilib directory. Remove the
shlib_so_soname substitution variable. Don't add a multilib encoding
to shlib_base_name. Set shlib_slibdir_qual to the full pathname
reported by -print-multi-os-directory. Pass @multilib_dir@ to
SHLIB_INSTALL as well as SHLIB_LINK.
* config/t-slibgcc-elf-ver (SHLIB_SONAME): Use @shlib_base_name@.
(SHLIB_NAME): Delete.
(SHLIB_DIR): New macro.
(SHLIB_LINK): Put $(SHLIB_SONAME) and $(SHLIB_SOLINK) in $(SHLIB_DIR).
(SHLIB_INSTALL): Adjust accordingly.
* config/t-slibgcc-darwin: As for t-slibgcc-elf-ver.
* config/t-slibgcc-sld: Likewise.
* config/t-libunwind-elf (SHLIBUNWIND_NAME): Delete.
(SHLIBUNWIND_SONAME): Use @shlib_base_name@.
(SHLIBUNWIND_LINK): Put $(SHLIBUNWIND_SONAME) and $(SHLIB_SOLINK)
in $(SHLIB_DIR).
(SHLIBUNWIND_INSTALL): Adjust accordingly.
* config/i386/t-nwld (SHLIB_SONAME): Delete.
(SHLIB_LINK, SHLIB_INSTALL): Use SHLIB_NAME instead of SHLIB_SONAME.
Use @shlib_base_name@ instead of @shlib_so_name@.
* config/ia64/t-hpux (SHLIB_LINK): Put @shlib_base_name@.so.0
and @shlib_base_name@.so in @multilib_dir@.
(SHLIB_INSTALL): Adjust accordingly. Add @shlib_slibdir_qual@
to the install path.
* config/mips/t-slibgcc-irix: As for t-slibgcc-elf-ver.
(SHLIB_LINK): Remove previous workaround.
* config/pa/t-hpux-shlib (SHLIB_DIR, SHLIB_SLIBDIR_QUAL): New macros.
(SHLIB_LINK): Put $(SHLIB_SONAME) and $(SHLIB_NAME) in $(SHLIB_DIR).
(SHLIB_INSTALL): Adjust accordingly. Add $(SHLIB_SLIBDIR_QUAL) to
the install path.
* config/rs6000/t-aix43 (SHLIB_LINK): Put @shlib_base_name@.a in
@multilib_dir@. Use @multilib_dir@ to check for threading libraries.
(SHLIB_INSTALL): Adjust accordingly.
(SHLIB_LIBS): Use @multilib_dir@ to check for threading libraries.
* config/rs6000/t-aix52: As for config/rs6000/t-aix43.
