Relicensing mempcpy, strchrnul, sysexists to LGPL

[Simon Law]

Hello,

I'm the maintainer for WvStreams, an LGPLed C++ networking library.

I'd like to include gnulib's argp implementation, for portability
reasons, but it depends on GPLed implementations of mempcpy, strchrnul,
and sysexits.

Looking at those files, they must have some less restrictive
implementation out there, because they are quite trivial.  Would it be
possible to relicense them under the LGPL?

Happy hacking,
