Brian Smith 8cffdc299f Issue #2051 - Part 1 - Initial changes to get UXP building on Mac 10.5 PowerPC.
Additionally update the version detection back to 10.5 and forward to 14.
Fill some parts with code from TenFourFox when changes are not obvious.
Using gcc 7 from MacPorts, the gcc 4.8 TenFourFox used is too old.
Don't use GNU as on MacPPC it is too old.
Fix struct/class sizes by limiting bool size.
