The question is whether we should have a similar mechanism for LFS (possiblity to build chapter 5 with makeflags only while building chapter 6 with makeflags and optimization, which is not possible presently AFAICT).
Another related and more general question is whether "make install" shouldn't always be run with -j1. Since the bottleneck is mainly I/O during installation, I would expect that the performance would not be significantly degraded. OTH, in some cases, packages which build OK with make -jN do not always install (see http://lists.cross-lfs.org/pipermail/clfs-dev-cross-lfs.org/2013-September/001720.html). It would be easy to change that in command generation. What do the others think ?
