[U-Boot] problem building fw_printenv

["Kári Davíðsson" <kari.davidsson@marel.com>]

I did not see real solution on the list, so i will post mine :)

The trick (for me) was to install the mtd-utils headers into the build environment.
I.e. install the contents of mtd-utils/include/mtd  into $(your_buildenv)/usr/include/mtd.
I had to to this manually, since make install of mtd-utils does not install the headers.

You will find mtd-utils e.g. at ftp://ftp.infradead.org/pub/mtd-utils/.
There is probably a git also for the mtd-utils.

I am using mtd-utils_1.0.0 and should upgrade but for now 1.0.0 will have to do.

Hope this helps others that will run into the problem and do not have "sane" build env.
