I would advise against doing that, considering that there are at least a handful of packages (can't name them) that have broken or otherwise malfunctioning Makefiles when run in parallel. The package maintainers _should_ be aware of those issues, and would accordingly add 'options="!makeflags"' to their PKGBUILD, but not everyone has a multiple core computer, nor did everyone test the functionality (there could be cases where -j4 runs fine, but -j8 crashes, or other weird race conditions). Adding your line as a mention in the makepkg.conf file (as a comment) could be a great idea, as it is definitely a clever way of automatically setting the number of parallel instances. #-- Make Flags: change this for DistCC/SMP systems # MAKEFLAGS="-j$(nprocs)" will set it to the number of logical cores on your system.
