auto-detect changed prefix and/or changed build flags
Detect changed prefix and/or changed build flags in the middle
of the build (or between 'make' and 'make install'), and if change
is detected, make sure all objects are compiled with same build
flags and same prefix, thus avoiding inconsistent/broken build.
[jc: removed otherwise unnecessary Makefile target to test the
change this patch introduces. ]
