Yeah, I posted that patch yesterday after realizing our
roms/vbootrom submodule is outdated.

Do I need to update vbootrom/ast27x0/Makefile?
I set "?=" to make user able to set variables in the command line.

The prob with `CC ?=` construct is that CC variable is always
set by make, so this line becomes useless.  The question mark
should be removed, that's all.

1.
export CC=aarch64-linux-gnu-gcc
make
2. make CC=aarch64-linux-gnu-gcc

3. Update Make file and user only need to issue "make"

See how it's done in other subdirs of vbootrom.  You only need
to remove ? from CC variable assignment.

Distinction between 1 and 2 is `make -e` command-line switch.

Thanks
