Would it be worthwhile to update the build system to support
installing both sets & automatically moving the necessary bits into
the alt-gcc-subdirectory?

Possibly similar to how isGCCAgnostic was implemented...
 * replace OptionalPackages & friends to use separate `if gcc2 ||
hybrid`,  `if gcc4 || hybrid` tests instead of the current if-else
logic.
 * include a 'gcc2' or 'gcc4' argument to indicate "built for gcc2" or
"built for gcc4" with the InstallOptionalHaikuImagePackage invocation
 * modify build_haiku_image::extractFile(), to perform magic. how --
i'm not sure yet.
