Build file cross compilation tool
Update nbsd_ports to account for new utils
Not every shell understands 'let'
Make mkfs.mfs cross compilable
Cross compile MFS ramdisk
Clean up generated files for ash,ramdisk,libutil,libc
Don't build ext2 ramdisk for cross compilation

. as mkfs.mfs is now cross compilable, we can remove the ext2 ramdisk
  special case for cross compilation.
mkfs.mfs: no need to include a.out.h
Release script: tools -> releasetools rename
Fix release script
generate offsets for ucontext.S
Decrease verbosity of devmand.

Display warnings(non critical errors) only when the verbose flag
is set.
Removed unused control fifo in devmand.
Adding a symlink from /usr/bin/strip to /usr/pkg/bin/strip.

When calling the new install with the -s (strip) argument it will
use the hard coded /usr/bin/strip unless a STRIP environment is set.
/etc/rc: use mount -a instead of manual parsing

The rc script manually parses /etc/fstab to mount all file systems.
To do that it needs /bin/sed which does not exist anymore. mount(8)
now supports the -a flag which causes it to mount all file systems
listed in /etc/fstab except for '/'. File systems marked with 'noauto'
are skipped.
setup: copy boot.cfg.default to /boot.cfg

This way the setup stays in sync with the source tree.
sed: add compatability symlink
Include bsd.own.mk in /usr/Makefile to have INSTALL_DIR defined.
sed: add compatability symlink properly
sed: unbreak crosscompilation
