autoconf build fail, only on Odroid-c1+

[manlyphall%manlymail.net@localhost]

Hi folks,

Is there anything out of the ordinary required to coax autoconf to build
on the Odroid-c1+?

Stable 7.0.2 and 2016Q4

I've been using the precompiled u-boot linked to on the evbarm
hardkernel wiki, as opposed to compiling my own.

I've tried completely fresh and I always get an error stating that sed
can find a file during configure.

Its very strange. Other packages build fine. But I am a little limited
without autoconf.

Any thoughts?
