[Buildroot] [PATCH] toolchain/buildroot: glibc does not always have native RPC

Starting with glibc-2.32, the RPC code has been removed from
glibc [0], and it is not possible anymore to enable it, even
with the --enable-obsolete-rpc configure option (which was
also removed).

riscv32 and arc both use a glibc 2.32+ so do not forecfully
enable native RPC for them.
