we shouldn't need to remove the build directory. Not removing it speeds up
the build considerably (we don't have to rebuild all of the Python bindings
just because the Makefile changed, for example).
svn path=/trunk/yasm/; revision=1486
CLEANFILES += python-setup.txt

- -rm -rf build
$(PYTHON) `test -f tools/python-yasm/setup.py || echo '$(srcdir)/'`tools/python-yasm/setup.py build
