buildgcc: move to a package centric user interface 

Instead of building IASL and GDB implicitly when building
GCC, this patch changes buildgcc to let you explicitly specify
what you want to build.

This will prevent IASL from building over and over again, when
all you need is GDB.

The new command line option is -P | --package <package> where
package is one of the following: GCC, GDB, CLANG, IASL
If no package is specified, buildgcc will default to GCC.
