I prefer to do this without any recompiling or reconfiguring of the
code.  For example, by having a dedicated environment variable or
command line argument that overrides the pkgdatadir value that has been
compiled into the program.  Rationale: I'd like to test, as much as
possible, the exact same code that is later being installed.

The Autoconf package itself does it this way, too: the tools wrappers
in the tests/ directory (generated from tests/wrappers.as) set
autom4te_perllibdir and a few other variables, and use -B aka.
--prepend-include.

Hope that helps.

Cheers,
Ralf
