[Buildroot] [git commit] package/gmp: fix compile error for riscv

[Thomas Petazzoni via buildroot]

commit: https://git.buildroot.net/buildroot/commit/?id=6d8deb4b23ee57a69308bcdc5ceafa02aacc1edd
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

In commit 87b2a30319394c2cc79efae1af7833cad8c62b32 gmp got updated
to 6.2.1, since then the compile error exist.

Compile error looks like this:
tmp-mul_1.s: Assembler messages:
tmp-mul_1.s:55: Error: unrecognized opcode `mul a5,a7,a3'
tmp-mul_1.s:57: Error: unrecognized opcode `mulhu a7,a7,a3'

Patch should be backported to stable branches.
