[Autoconf-patches] Re: libelf and fileutils

Thanks for noticing and reporting it!

Here's the patch:

        * getloadavg.m4 (AC_FUNC_GETLOADAVG): Restore the initial value of LIBS.
        Otherwise, everyone ends up linking with -lelf for some configurations.
        Reported by Mike Stone.

And since my getloadavg.m4 is very similar to what's in autoconf's
acfunctions.m4, the latter needs the patch, too.  Here it is:
