package/gnu-efi: get rid of patch

Pass TARGET_CONFIGURE_OPTS in the environment instead of on the make command
line, so 'CFLAGS +=' does the right thing in the Makefile without patching.

TARGET_CONFIGURE_OPTS includes TARGET_MAKE_ENV, so drop that.

This does require us to pass CROSS_COMPILE to ensure the native tools are
not used though.

Add a GNU_EFI_MAKE_OPTS and use in both the build and install steps, instead
of repeating the various arguments.

-Subject: [PATCH 1/2] Allow CFLAGS/CPPFLAGS to be completed from the
- environment
-
-Buildroot passes its own CPPFLAGS and CFLAGS in the environment, so
-the CFLAGS += and CPPFLAGS += statements in gnu-efi Makefile have no
-effect. Change these to override <VARIABLE> += so that they extend the
-flags passed by Buildroot.
