If you've been reading lfs.chat, you'll know that I am building LFS 5.0
on an i386/DX-20. Native. If not, check out
http://www.manik.mina.dsl.pipex.com/lfsbuild/. You'll see that the first
package, Binutils, took 3.25 hours just to un-pack. Four hours is no
time at all!
I have just completed building the Temporary System on an i486/DX4-100
with 64 MB RAM - this took a total of 3 days. I estimate the rest of the
build would take about 3-4 days. My recommendation would be to forget
the cross compiling and build LFS 5.0 straight on to your 486. Even if
it was a lowly 25 MHz version, it would probably only take 3 weeks at
most. You'll also be guaranteed 100% i486 code as well ;-)
