Title: Updated formula: graphicsmagick

Fix for graphicsmagick on Lion, as llvm causes errors:

Undefined symbols for architecture x86_64:
"___builtin_object_size", referenced from:
_DespeckleImage.omp_fn.5 in magick_libGraphicsMagick_la-effect.o
_BlurImageScanlines.omp_fn.7 in magick_libGraphicsMagick_la-effect.o
_XShearImage.omp_fn.0 in magick_libGraphicsMagick_la-shear.o
_YShearImage.omp_fn.1 in magick_libGraphicsMagick_la-shear.o

Without this clang workaround, copied from pixman.rb, this formula does not work.
