the src/ tree into a directory that contains files/directories, such
as a case where a custom kernel configuration file is specified.
- Allow specification of multiple KERNCONFs to pass to 'make release'.
- Move evaluation of NODOCS/NOPORTS earlier, and set based on how the
release process expects these options to be evaluated.
- Wrap KERNCONF specification in double quotes, and use 'eval' so multiple
kernel configurations do not cause the build to fail in strange ways.
- Set WITHOUT_X11 for the port build flags for the documentation toolchain
build. Also run 'clean distclean' targets during port build.
