[PATCH 1/2] Fix python client cross compile

The setup.py setuptools wrapper needs to use a version of python built
specifically for cross compiling to cross compile successfully. Allow
setting that in the environment using the SETUPTOOLS_ENV variable.

Fixes the following build failure:

/usr/bin/ld: skipping incompatible .../lirc-tools-0.10.0/lib/.libs/liblirc_client.so when searching for -llirc_client
/usr/bin/ld: cannot find -llirc_client
collect2: error: ld returned 1 exit status
error: command '/usr/bin/gcc' failed with exit status 1
Makefile:1578: recipe for target 'all-local' failed
