	-i	Fast incremental options (no clobber, lint, check)
	-n      Do not do a bringover
	+t	Use the build tools in $ONBLD_TOOLS/bin
	-V VERS set the build version string to VERS

	it will be looked for in $OPTHOME/onbld/env.

non-DEBUG is the default build type. Build options can be set in the
NIGHTLY_OPTIONS variable in the <env_file> as follows:

	-A	check for ABI differences in .so files
	-C	check for cstyle/hdrchk errors
	-D	do a build with DEBUG on
	-F	do _not_ do a non-DEBUG build
	-G	gate keeper default group of options (-au)
	-I	integration engineer default group of options (-ampu)
	-M	do not run pmodes (safe file permission checker)
	-N	do not run protocmp
	-O	generate OpenSolaris deliverables
	-R	default group of options for building a release (-mp)
	-U	update proto area in the parent
	-V VERS set the build version string to VERS
	-X	copy x86 IHV proto area
	-f	find unreferenced files
	-i	do an incremental build (no "make clobber")
	-l	do "make lint" in $LINTDIRS (default: $SRC y)
	-m	send mail to $MAILTO at end of build
	-n      do not do a bringover
	-o	build using root privileges to set OWNER/GROUP (old style)
	-p	create packages
	-r	check ELF runtime attributes in the proto area
	-t	build and use the tools in $SRC/tools (default setting)
	+t	Use the build tools in $ONBLD_TOOLS/bin
	-u	update proto_list_$MACH and friends in the parent workspace;
		when used with -f, also build an unrefmaster.out in the parent
	-w	report on differences between previous and current proto areas
	-z	compress cpio archives with gzip
	-W	Do not report warnings (freeware gate ONLY)
	-S	Build a variant of the source product
		E - build exportable source
		D - build domestic source (exportable + crypt)
		H - build hybrid source (binaries + deleted source)
		O - build (only) open source
