You almost had it. :-) The semicolons in the above command line make it
such that, for example, "GNC_UNINSTALLED=1" is its own (no-op) command that
does not affect the python command.

Try this in your virtual environment:

(gnucash-build) robg at kubuntu01:~/gnucash-build$ GNC_UNINSTALLED=1
GNC_BUILDDIR=`pwd` python3

Python 3.6.9 (default, Apr 18 2020, 01:56:04)
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

>>> print(gnucash.gnucash_core_c.CREC)
c

I don't know what the deal with the preference backend stuff is, but maybe
it won't affect your testing.
