You cannot/should not run multiple "configure" in parallel in the same
directory. This is due to a limitation of the autoconf framework that we
are using -- they test features (like word size) by creating a file in
the current directory (conf.c I believe it's called), compiling and
running it. So if you run multiple configure calls in parallel, these
tests can interfere with each other.
Once the configure step is done, you can build multiple configurations
using "make" at the same time.
