Yes,

Some embedded use cases are highly size constrained. Buildroot[1] supports 
building lirc with with various optional dependencies[2] to reduce the size of 
the final image. This patch allows update to the 0.10.0 release, while having 
python as an optional dependency.

The configure.ac/Makefile.am code itself indicates that the python dependency 
is meant to be optional, depending on HAVE_PYTHON35.

Unrelated to that I hit another cross compile issue with setuptools while 
trying to build with python enabled. I'm still investigating that one.
