Clean slating the gcc directory
* Keeping gmp, mpc, and mpfr
* Blowing away GCC 4.6 files before importing pristine GCC 4.7 files
Initial import of GCC 4.7.2 files
* GCC no longer provides separate packages for things such as core and g++ anymore
* This commit has all the GCC files, even ones we don't need to build Haiku
* The next commit will remove unneeded files, like those for Fortran, Java, etc.
Remove GCC packages not needed for building Haiku
* These include Ada, Fortran, Go, Java, ObjC, and Testsuite
* This makes the directory listing equivalent to what used to be Core and G++
Initial patch to apply Haiku compatibility
* This is the bulk of changes, but there will be subsequent fixes
