[Bug-ed] [PATCH] configure: respect user env settings

[Mike Frysinger]

First we have to fix the locale otherwise some of the arg parsing may fail.
This NLS code is taken from latest autoconf-2.63.

Then we fix the toolchain related variables to respect the user build
settings.  This makes the configure script behave just like an autotooled
one.
