I just hope that everything works for you when Xorg has been
installed.  Building everything in a tty is a valid approach, but it
becomes painful if you ever build a complete system and then find
that startx (or a DM) does not work.

I would definitely drop radeonsi, dropping nouveau will do no harm
if you don't use nvidia cards.  And I suppose drop -lLLVM.  But give
it a (logged) build in case other changes are necessary.

I don't recall the details of pre-meson Mesa versions, everything in
its build has changed - but I'm not sure if the version of meson in
LFS-8.4 is good enough for recent Mesa, there have been some
"interesting" issues in Mesa and meson.
