build/maint.mk: Comment out setting of LC_ALL

This triggers obscure bugs; really we shouldn't be overriding
the global locale here.  In practice, production build systems
will be using fixed locales anyways.

Also, we only use a small subset of this file (`make syntax-check`),
which appears to work OK without this.

I will probably try to work out where to submit this as at
least an issue report for upstream gnulib.
