[Buildroot] [PATCH 1/2] support/scripts/gen-bootlin-toolchains: riscv32 use a pre-2.33 glibc version without RPC support

riscv32 has been merged into glibc 2.33 where RPC support has been removed [1].

Add a special handling for the riscv32 Bootlin bleeding-edge 2020.08-1 toolchain
since it used a re-2.33 glibc version where RPC support has been removed [2].

Other glibc Bootlin toolchain use glibc 2.31 with RPC support enabled.

This special handling must be removed when all Bootlin toolchain has been
rebuild with glibc > 2.32.
