The logic in gen-bootlin-toolchains was assuming all glibc toolchains
have RPC support, which is no longer true since glibc 2.32 has dropped
RPC support.
It turns out that gen-bootlin-toolchains already had some proper logic
that selects BR2_TOOLCHAIN_HAS_NATIVE_RPC depending on the presence of
BR2_TOOLCHAIN_EXTERNAL_INET_RPC in the toolchain fragment. As such
toolchain fragments have been fixed in https://toolchains.bootlin.com,
we can now rely on this to properly decide if the toolchain has RPC
support or not.
