[PATCH 01/26] EmulatorPkg: require GCC48 or later

[Laszlo Ersek <lersek@redhat.com>]

We're about to remove BaseTools support for GCC44..GCC47. Reject those gcc
versions cleanly in "EmulatorPkg/build.sh", and drop build flags too that
are specific to them.

No GCC44..GCC47 references remain under EmulatorPkg after this patch.

Notes:
    I tested that, after this patch, "build.sh" successfully builds
    EmulatorPkg with GCC48. I did no runtime tests, nor did I test the
    rejection path with any of gcc-4.4 through gcc-4.7.
