Argh, so they brought back RPC support into glibc... sigh.

I'm a bit hesitant here. If newer glibc toolchains re-include the RPC
support, is it worth supporting libtirpc and do all the changes I had
proposed? Or should we just give up and say we only support
glibc toolchains that include RPC support? Maybe not nice, since
libtirpc brings quite a few features compared to in-toolchain RPC
support.

Comments from others?
