Sorry, the first problem is that make doesn't descend into the "env"
subdirectory when building (hence the addition of "env" to TOOLSUBDIRS
in "tools/Makefile"). The second problem is that the env subdirectory
is not set up for cross-compiling properly - it uses the hosts gcc
when building the dependencies, as well as different compiler flags.
The third problem was that a user level program should not include
linux kernel header files. Hence the change from <linux/mtd/mtd.h>
to <mtd/mtd-user.h>.

Hmm.. I use OpenEmbedded for cross compiling. This file is installed into
the OpenEmbedded cross compiling includes area as part of the building of
the OE "mtd-utils" package (check out http://www.linux-mtd.infradead.org/).
