Details:
Building grub2 for armv7a arch would fail with the following errors.
| build-grub-module-verifier: error: unsupported relocation 0x2b.
| make[3]: *** [disk.mod] Error 1
| make[3]: *** Waiting for unfinished jobs....
| build-grub-module-verifier: error: unsupported relocation 0x2b.
| make[3]: *** [cat.mod] Error 1
| build-grub-module-verifier: error: unsupported relocation 0x2b.
| make[3]: *** [cmp.mod] Error 1
I'm using gcc 5.3 for cross compilation.
"arm-poky-linux-gnueabi-gcc -march=armv7-a -marm -mfpu=vfp
-mfloat-abi=softfp ...."
I've looked at the codes of grub-module-verifier. The problem seems to be that
the above relocation is not allowed for 'arm' arch. Add the relocations for
arm arch would solve the build failure but I really don't know whether it's
appropriate.

To summarise, is the above patch appropriate or armv7a is not yet supported?
