KEYBOARD_MAP "fr" issues

[NiKiZe]

There is discussion at http://lists.ipxe.org/pipermail/ipxe-dev...00407.html
Which refers to it being autobuilt, which might be why the documentation is minimal, commit at https://git.ipxe.org/ipxe.git/commitdiff...ffc63195a5
The interesting part is a few commits just before: https://git.ipxe.org/ipxe.git/commitdiff...4fcb3672ca
Which in turn refers to /util/genkeymap.pl - which has some documentation, and probably is what you actually want to run.

But other than that I can't find much information, so an update of https://ipxe.org/buildcfg/keyboard_map is in order, i will ping mcb about it
