Using 'make -jX' (X = number of cores + 1) significantly helps, but I
suppose you may know it already. If you have other machines, distcc is
also a great help (it is a great delight when one executes 'make -j22').

With Linux it is not necessary. I simply run
kicad_src/build/pcbnew/pcbnew and it works fine. Note that if you want
to use features from another application (e.g. footprint previewer in
eeschema depends on pcbnew) you need to create appropriate symlinks. I
do the following:
$ cd build/kicad # kicad launcher build directory
# create symlinks for *kiface files
$ find .. -name "*kiface" -exec ln -s \{\} \;

As you have noticed, full rebuilds happen only when you touch one of the
ubiquitous headers. The build time has been already improved by
splitting the big headers and cleaning up redundant #include directives,
but I am sure there is still some work to do.

Yes, you may either run 'make' in build/pcbnew directory or run 'make
pcbnew'.

See the note about creating symlinks, it should solve the problem.
