Since commit f590a812c2 we build the EDK2 EfiRom utility
unconditionally.
Some distributions require to use extra compiler/linker flags,
i.e. SUSE which enforces the PIE protection (see [*]).
EDK2 build tools already provide a set of variables for that,
use them to allow the caller to easily inject compiler/linker
options..
Now build scripts can pass extra options, example:
$ make -C roms \
EDK2_BASETOOLS_OPTFLAGS='-fPIE' \
efirom
