libx86 is a dependency of vbetool. Since the new release of vbetool it
is split of in a different library, packaged in a different tarball. We
probably wont be doing much development on libx86 so Stefan purged that
part from CVS. People compiling will now need to get the tarball from
Matthews website.
So far so good.
Now I would argue: let people just get that tarball, unpack, type make
&& make install, just like they would for liblzf or libgcrypt.
Stefan however, has implemented a hack to help people compile suspend
in one go. You know can unpack the tarball, make a symlink and type
make.
I was arguing that was unnecessary, and would just clutter our makefile.
Well, I'm not going to get religious over this, I made a patch that
keeps stefans idea, but makes it a bit better to read (IMHO), it also
makes it a bit easier to add other CONFIG_EMBEDDED_ stuff and will help
with my ppc-support patch that I will send in a few days.
I also removed some cruft left over from the pre-libx86 days.
OK, to commit?
