grub_git: remove armv7a from COMPATIBLE_HOST

1.9.1

grub_git recipe supports arm architectures. However, when building against armv7a arch, we would meet the following error.

| 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

This address, along with 0x2c, is not supported yet, according to grub upstream.

So remove armv7a from COMPATIBLE_HOST for now.

Unless you have verified that armv4, armv5, armv6 and armv7ve all work correctly then blacklisting only armv7a is probably not the correct approach.
