GCC: disable MASK_RELAX_PIC_CALLS bit

The new feature added after 4.3.3
"http://www.pubbs.net/200909/gcc/94048-patch-add-support-for-rmipsjalr.html"
will cause cc1plus eat up all the system memory when build webkit-gtk.
The function mips_get_pic_call_symbol keeps on recursively calling itself.
Disable this feature to walk aside the bug.
