(LINK_SPEC): Do not depend on gas.

(LINK_SPEC): Do not depend on gas.  Don't interpret -EB
and -EL options, but do pass them.
(ASM_SPEC): Make definition depend on whether or
not the default assembler is gas.  Pass all normal assembler
options to gas.
(ASM_FINAL_SPEC): Cross compiling does not presume gas.
