[Distutils] Fixing distutils bug #668662 before Py2.3a2

Hi, I have uploaded a patch fixing distutils bug #668662 and I am wondering if it is possible to apply it before Py2.3a2 is released (that should happen today according to GvR). This bug fix is crusial for those extension module builders who specify source codes with absolute paths and don't have write permissions to the location of source codes (the bug is that Py2.3a1 distutils forces the corresponding object files to go to the source directory, not to the build directory where they should go). Thanks, Pearu
