Yann will confirm or infirm, but since the glibc version selection is
not done in Buildroot, but directly inside Crosstool-NG, there is no
way for Buildroot to automatically now if the glibc of the toolchain
will have RPC support or not. Therefore, the only practical solution is
to have an option similar to the one we have in external toolchain,
where we leave it to the user to say whether the toolchain generated by
Crosstool-NG will have RPC support or not.

However, I haven't thought in detail about the detailed impact on the
implementation.
