In a cross-build, the build-tools are native host binaries. We do not want to rebuild them when building for the target. Bmake previously did not support checking .NOMETA on an existing target, so .NOMETA_CMP was used here. However, .NOMETA_CMP still triggers meta mode conditions if the number of commands or the command changes. In r312467 the paths to build ncurses files were modified and thus triggered meta mode to rebuild the build tools (make_keys, make_hash) in ncurses during the target build. Bmake 20160604 committed in r301462 changed .NOMETA to also skip meta mode logic for an existing .meta file as well, thus it is now the proper fix here. I explored moving the build-tools output to WORLDTMP/tools with relatively good success, but have concerns that doing so would be problematic for downstream vendors who use LOCAL_TOOL_DIRS and expect the tools to be in current OBJDIR for the target. It also adds more complexity into finding the tools during target build and handling of where they are for rescue/rescue and mkcsmapper_static/mkesdb_static which should really not be connected in build-tools anyway.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
