toolchain-external: improve glibc support to test availability of RPC
Basically, the BR2_TOOLCHAIN_EXTERNAL_GLIBC option no longer unconditionally selects BR2_TOOLCHAIN_HAS_NATIVE_RPC since there are glibc toolchains that don't have RPC support. All the predefined toolchain profiles are updated to take into account this change: for the moment, all glibc toolchains that have pre-defined toolchains have RPC support, but further patches in the series add pre-defined glibc toolchains that don't have RPC support. In the case of custom glibc toolchains, a question is asked to the user so that he can say whether the external glibc toolchain has RPC support or not. The validity of this configuration option is checked by the new check_glibc_rpc_feature function in helpers.mk.
