test: Add test for builds with -DNDEBUGndebug

Since bc872d91765d we omit assert()s if the NDEBUG preprocessor symbol is
defined, as is the case with the standard library assert(3).  However,
none of our tests verify that we can actually build that way.  Add an
extra test to test/build/build.py tto verify this.

Fixes: bc872d91765d ("treewide: Spell ASSERT() as assert()")
