Fix install location for Python bindings
Commit 66137344feb488ea87b0d92f3c03844d9a7a7786 changed the Python detection mechanism in configure to use AM_PATH_PYTHON. This results in a changed install location for the Python bindings, at least on Fedora 12 64bit systems. Before this commit libvirt.py and libvirtmod.so were installed to /usr/lib64/python2.6/site-packages After this commit they are installed to /usr/lib/python2.6/site-packages Mixed Python packages (containing *.py and *.so files) should be installed to the pyexecdir directory detected by AM_PATH_PYTHON. This restores the install location from before the AM_PATH_PYTHON commit. * configure.in: remove unnecessary pythondir export * python/Makefile.am: switch from pythondir to pyexecdir
