+-undefined error is the equivalent of --no-undefined for the macOS
+linker, but -undefined would also be understood as a valid argument for
+GNU ld so we use the supported linker variant.

+Subject: meson: Fix cell overflow tests when running from meson
+
+Because meson always builds out-of-tree we need to reference things in the
+original source tree via $SRCDIR from run_tests.sh.  We forgot a couple of
+cases for the cell overflow tests.  Fix them.
