src/usr.sbin/mdsetimage has been superseded by src/gnu/usr.sbin/mdsetimage
for toolchain to handle cross build binaries, but these old sources for
local executable binaries still can be used for tools to patch binaries,
like binpatch utility in sys/arch/amiga/stand and sys/arch/atari/stand.
The purpose of that modification is to make the license on these files
"GPL-compatible," so that mdsetimage may be combined with BFD. (The
resulting license is word-for-word identicial to one of the licenses
described as being GPL compatible on
http://www.gnu.org/licenses/license-list.html.)
