[patch] More on HP weak symbols

[Catherine Moore <clm at cygnus dot com>]

A couple of months ago, I submitted some patches to support weak
symbols on hp platforms.  A problem was discovered where a weak
symbol in an archive was not being used to satisfy a reference.

For ELF, the scope of symbol can be GLOBAL, WEAK or LOCAL.  For
SOM, the scope is GLOBAL or LOCAL and weak is something else
altogether.  The routine S_SET_EXTERNAL in symbol.c assumes
that global symbols can't be weak.  This is wrong for this
platform.  

Okay to commit?

	* config/tc-hppa.c (pa_export): Weak symbols can be global.
