Regenerate for:

        * acinclude.m4 (GMP_TRY_ASSEMBLE): Make conftest.out available.
        (GMP_ASM_ALIGN_FILL_0x90): Use it.

        * acinclude.m4 (GMP_ASM_X86_MMX) [*-*-solaris*]: Check for solaris
        2.6 "as" movq bug.

        * configure.in (alphapca56*-*-*): Use ev5 mpn path.
        (am29000*-*-*): Remove this, leave the canonical a29k.
        (z8k*-*-*, z8kx*-*-*): Changed from z8000, since z8k is canonical.
        (gmp_mpn_functions_optional): Add invert_limb, use for alpha and ia64.

        * configure.in (alloca): Accept yes/no/detect, generate an error if
        "yes" but not available.
