acconfig.h (HAVE_GAS_WEAK): New define.

Browse Source 
* acconfig.h (HAVE_GAS_WEAK): New define.
        * configure.in (assembler weak support): Check for .weak support.
        * config.in, configure: Rebuilt.
        * pa/som.h (MAKE_DECL_ONE_ONLY, ASM_WEAKEN_LABEL): Only define if
        HAVE_GAS_WEAK is defined.
