Makefile.inc: Avoid --emit-relocs on RISC-V

There seems to be a bug[1] in the GNU linker for the RISC-V architecture
triggered by symbols that are more than 2GB offset from the program
counter. My next patch is introducing symbols like that and stuck on
this problem. The code path that runs into the issue is only taken when
passing the --emit-relocs flag, which is really only needed for building
rmodules. Since RISC-V platforms don't use any rmodules at the moment,
let's disable the flag on RISC-V until the issue can be fixed in the
toolchain.
