That would probably be a very good idea, to avoid mixing files built for 
one mode with files built for another.  Even easier:  use separate build 
directories for each type, from a common source directory, like so:

$ : ... starting one directory above the source tree in ./src/ ...
$ (mkdir test-build; cd ./test-build && ../src/configure --enable-assert 
...)
$ (mkdir release-build; cd ./release-build && ../src/configure 
--disable-assert ...)

Now you avoid conflating modules for test and release builds and ending 
up with an executable that you cannot reliably replicate.  A simple flag 
to make is unlikely to be properly recognized as a dependency for all 
objects built.
