There are three uses of that PYTHON setting across workdir/UnpackedTarget/icu:

1  In source/configure.ac to generate source/data/rules.mk if
source/data/locales/root.txt would exist---but which doesn't, so we don't
actually need PYTHON there.

2  In source/configure.ac to generate source/test/testdata/rules.mk, but which
our (non-check) build apparently doesn't need anyway.

3  In source/data/Makefile.in for target check-local, which is a sub-target of
check (which we don't build).
