This patch adds RISC-V to the COMPATIBLE_HOST. Since GRUB 2.04,
the source code supports the RISC-V, thanks to Alexander Graf.
Adding the GRUBPLATFORM for RISC-V prevents autoconf problems.
Also, the patch appends the __anonymous method with RISC-V architecture.

RV64 is file but does it also support RV32 ?
I see that there are some changes for RV32:
https://git.savannah.gnu.org/cgit/grub.git/tree/configure.ac?h=grub-2.04#n186
And I'm able to build the grub and grub-native package for RV32.
There is a problem with grub-mkimage for RV32 in grub-efi,
it fails with the error:
grub-mkimage: error: target 1f46 not reachable from pc=10b6.
This points to the line:
https://git.savannah.gnu.org/cgit/grub.git/tree/util/grub-mkimagexx.c?h=grub-2.04&id=3562536fd5e5cc3d40942f3e8ac53d4f0ee5c220#n1300
I guess for now, we should leave the support only for the RV64,
which is tested and works well.
else:
raise bb.parse.SkipRecipe("grub-efi is incompatible with target %s" %
target)
