gcc:
* config.gcc (i[34567]86-*-linux*): Handle --enable-targets=all.
Handle tuning for bi-arch i[34567]86-*-linux* like that for
i[34567]86-*-solaris2.1[0-9]*.
* config/i386/linux64.h (TARGET_VERSION, MULTILIB_DEFAULTS):
Define conditionally depending on TARGET_64BIT_DEFAULT.
(SPEC_32, SPEC_64): Define.
(LINK_SPEC): Use them.
* doc/install.texi (--enable-targets=all): Document for x86-linux.
libcpp:
* configure.ac (need_64bit_hwint): Set for i[34567]86-*-linux*
depending on --enable-targets=all.
* configure: Regenerate.
fixincludes:
* inclhack.def (AAB_fd_zero_asm_posix_types_h): Bypass on x86_64.
* fixincl.x: Regenerate.
