This commit gets Mac PowerPC to initialize and shows the menubar. Hangs in font code before showing the window, but this is progress. Remove workaround for a GCC structure packing bug, use fixed GCCs. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110044 Fix linking altivec code with some compiler versions. Restore the old "CoreGraphics" GFX backend; SKIA unsupported 10.5. https://bugzilla.mozilla.org/show_bug.cgi?id=1258751 Similarly restore code to display popups/panels with "CoreGraphics" https://bugzilla.mozilla.org/show_bug.cgi?id=1274720
