Since I have not been able to track down the SRPMs in order to rebuild
ELDK 4.1 from scratch, I'm giving ELDK 4.2 a try.  This changes a few
more variables than I would like, but such is life.

Following the build instructions, I'm getting a compile problem in the
libelf library use by RPM when I compile on either Ubuntu Server or
Fedora 9.  The error appears to be related to conflicts between an
extern declaration, an inline defintion, and an out of line definition
of the dwarf_whatform() function.  If I recall correctly, there have
been changes in gcc's inline semantics that may be responsible, so I'm
hoping that using an older OS version will result in a clean rebuild.

I've checked the wiki/manual, but didn't find a mention of the
canonical build host used for ELDK builds.  I'd like to just grab the
same distribution, load it up on a VM host, and use that.

Many thanks once again,
