[PATCH] Unexport LANG env variable

[Alexey Brodkin <Alexey.Brodkin@synopsys.com>]

In those cases when we parse output of standard utilities like readelf
etc we rely on a particular sentences. For example for ARC we extract
an entry-point from vmlinux like that:
---------------------->8--------------------
readelf -h vmlinux | grep "Entry point address" | grep -o 0x.*
---------------------->8--------------------

And in case LANG is set to anything other than en_XX we're getting
nothing and subsequent execution of mkimage utility fails.

Probably there're more cases like that but given people rarely
use non-English locales on their dev machines problems like the one
above are not very visible.
