The rpc PACKAGECONFIG regenerates rquota.{c,h} and rquota_clnt.c from
rquota.x with rpcgen at build time, as the tarball ships no
pre-generated copies. Two problems made this fail:

- rpcgen was picked up from the host via HOSTTOOLS rather than from the
  build, which is non-deterministic and breaks on hosts that have no
  rpcgen at all.

- rpcgen execs its C preprocessor as a single program name, but OE
  exports $CPP as a multi-word "gcc -E --sysroot=... <flags>" string,
  so rpcgen reports "cannot find C preprocessor" and aborts.

Depend on rpcsvc-proto-native so rpcgen comes from the build, and set
RPCGEN_CPP to the single-word cross cpp so the preprocessor can be
exec'd.

Tested with bitbake quota (configure/compile/install/package) on
qemuarm.
