[bug#35966] [PATCH] gnu: Add basic support for riscv64-linux-gnu targets.

[Carl Dong]

From: Carl Dong <address@hidden>

Aside from this patch, we also need 35888 and 35963 to satisfy riscv64's minimum
kernel header version requirements.

* gnu/packages/bootstrap.scm (glibc-dynamic-linker): Add
  "riscv64-linux".
* gnu/packages/linux.scm (system->linux-architecture): Add "riscv"
  prefix.
