component/gmp: version up and disable assembly

Since gmp is used by nft and nft is used by firewalld which is included
in slapos-node package, we need to have support for all CPU (disable-assembly).
Otherwise, you can see this kind of errors in dmesg:

firewalld[16932] trap invalid opcode ip:7f5f26ad61fb sp:7fff95cf7480 error:0 in libgmp.so.10.3.1[7f5f26ac7000+51000]

Note that --host=none-pc-linux-gnu is needed to enable the shared libraries.
