rpcgen normally runs with a hardcoded cpp path of e.g. /lib/cpp,
but not all Linux distributions install a cpp there.
Grab a trick from glibc, and run rpcgen with a cpp-path pointing at
a script; the script then runs the cpp specified in the CPP
environment variable - which was set by the configure script to
something reasonable.
