[LEDE-DEV] libelf1 build error for MT7688 board

[Vivian Noronha]

Hello,

I am working with MT7688 board (Linkit Smart 7688) and while compiling
the library and building the firmware with LEDE project. I am facing
with the error message in the elfutils as shown below:

OS used: Ubuntu 14.04
My questions are
Is this the right place to report this?
how can the error be rectified?
If more info is needed i can provide.

Cheers,
