[Buildroot] make menuconfig in a buildroot env.

[Thomas Lundquist]

I've made a buildroot development environment and have a buildroot
checkout in it.

I've done this many times before but since the last time I did it, this
have started to happen:

It is not the ncurses library since another (earlier) br2 I have works in 
the same built rootfs.
