buildgcc: Make package build() function more versatile

Refactor build() to make things more flexible:

Add a parameter that tells if we build a package for the host or for a
    target architecture. This is just passed to the build_$package()
    function and can be used later to take different steps in each case
    (e.g. for bootstrapping a host gcc).

Move .success files into the destination directory. That way we can tell
    that a package has been built even if the package build directory has
    been removed.
