The net library is configurable on vxworks7. Pick the library
to include in link closures in accordance with the availability
of a revealing header file, using the recently introduced 
if-exist-then-else spec builtin function.

Tested on a mix of gcc-9 and gcc-10 based builds for Vxworks7r2,
and sanity checked that a powerpc-vxworks build passes for languages=c,c++
with mainline sources.

Committing to mainline.

	* config/vxworks.h (VXWORKS_NET_LIBS_RTP): Use -lrtnet if
	rtnetStackLib.h is available, fallback to -lnet otherwise.
