Because the internal RPC implementation is mostly useless and
getting removed?

The idea was to entirely remove BR2_TOOLCHAIN_HAS_NATIVE_RPC in
further patches. This would involve to disable deprecated RPC in
internal Glibc and uClibc-ng toolchains. 
I think RPC support in external toolchains will disappear when
GNU C library will finally remove the code.
