$ cd $SRC
$ make kernel-toolchain TARGET_ARCH=armXX
$ make buildenv TARGET_ARCH=armXX BUILDENV_SHELL=/usr/local/bin/shell
$ cd <moduledir>
$ make
The buildenv command sets up the new shell with an environment that is
the same as if you were running under a buildkernel or buildworld
environment.. You can use this to build one off programs like bin/ls
too.
