[PATCH 2/5] configure, test: Added variables for paths to true and false.

[Charles Celerier]

The path to true may not be the same on all platforms (e.g. on Mac OS X
it is /usr/bin/true), so the hard-coded path of /bin/true is not
portable. This is resolved by adding a step to the configure script to
locate the path of true and to use the TRUE variable wherever /bin/true
was needed. The same was done for false.
