Remove rpcgen __GNU_LIBRARY__ conditionals

["Joseph S. Myers" <joseph at codesourcery dot com>]

The rpcgen code has various conditionals on __GNU_LIBRARY__.  These
conditionals all relate to the target (generating code for use with
glibc), not the host, in a cross-compilation scenario.  It's not the
job of glibc to provide a version of rpcgen that covers non-glibc
targets (and I doubt libtirpc will really care to do so either - not
that many of the conditionals are actually likely to cause problems
for many non-glibc targets anyway).  I propose this patch to remove
those conditionals, so avoiding any issues with cross-rpcgen on a
non-glibc build system generating files different from those when
glibc is built on a glibc build system.

Tested x86_64.

	* sunrpc/rpc_cout.c: Remove __GNU_LIBRARY__ conditionals.
	* sunrpc/rpc_main.c: Likewise.
	* sunrpc/rpc_svcout.c: Likewise.
