I have upgraded the h/w in one machine. Now it make sense to change the
"chost" and "march".

Are there any considerations here? I am concerned that programs may be
looking for a specific directory for things like glibc libraries and fail
to find them.

I have read that you must only change the CHOST setting for a stage 1
install, which pretty much rules out changing it on a new machine. Changing
march makes sense though, and will only be a setting for newly compiled
things, I don't think it could break anything unless you're using unstable
optimisations.

You will need to run fix_libtool_files.sh when you change the CHOST. As
for updating the CFLAGS, 'emerge -e world' should recompile everything
to use the new flags. You could also just let it be and let the
inevitable updates do it for you, though it'll take a bit longer! :-)
