Setting the --target-efi option for any architecture but x86_64 results in
an error while trying to compile the tests:
$ ./configure --arch=arm64 --cross-prefix=aarch64-linux-gnu- --target-efi
$ make clean && make
Makefile:46: *** Cannot build aarch64 tests as EFI apps. Stop.
Which might come as a surprise for users, as the help message for the
configure script makes no mention of an architectur being incompatible
with the option.
Document that --target-efi applies only to the x86_64 architecture and
check for illegal usage in the configure script, instead of failing later,
at compile time.
