[PATCH] x86: Fix gcc 4.2 _proxy_pda workaround
Due to an over aggressive optimizer gcc 4.2 cannot optimize away _proxy_pda
in all cases (counter intuitive, but true). This breaks loading of some
modules.
The earlier workaround to just export a dummy symbol didn't work unfortunately
because the module code ignores exports with 0 value.
Make it 1 instead.
