[PATCH] xtensa: fix libgcc build with --text-section-literals

[Max Filippov]

Functions __muldf3_aux, __divdf3_aux, __mulsf3_aux and __divsf3_aux
don't start with leaf_entry, so they need explicit .literal_position,
otherwise libgcc build fails in the presence of --text-section-literals.

        * config/xtensa/ieee754-df.S (__muldf3_aux, __divdf3_aux): Add
        .literal_position before the function.
        * config/xtensa/ieee754-sf.S (__mulsf3_aux, __divsf3_aux):
        Likewise.
