While building fairly large pieces of software like an
entire UNIX system, kernel, commands, libraries, and
everything, from source, we found that a good way of
speeding everything up was to set up a minimum size
environment (about 5 variables), then use 'ksh' as the shell
that 'make' used all the time. This produced about a 1/4
faster build (knocked about 90 mins off a six-hour build
time). Of course, most of what 'make' does is 'exec' a
shell...
