Per Bothner ab16524d62 configure.in: FILE variable overrides FLATFORM when linking natFileChannelXXX.cc. 
* configure.in: FILE variable  overrides FLATFORM when linking
	natFileChannelXXX.cc.

	* gnu/java/nio/channels/natFileChannelEcos.cc (diag_write):  Restored.
	(write):  Call diag_write, as in old natFileDescriptorEcos.cc.

# 1. Use "connect" and "accept" to check for -lsocket, and
# "gethostbyname" to check for -lnsl.
# 2. Use each function name only once: can't redo a check because
# autoconf caches the results of the last check and won't redo it.
# 3. Use -lnsl and -lsocket only if they supply procedures that
# aren't already present in the normal libraries. This is because
# IRIX 5.2 has libraries, but they aren't needed and they're
# bogus: they goof up name resolution if used.
# 4. On some SVR4 systems, can't use -lsocket without -lnsl too.
# To get around this problem, check for both libraries together
# if -lsocket doesn't work by itself.
