Review request for Build System.


Description
-------

Currently, pykdeuic4.py is symlinked to BIN_INSTALL_DIR as pykdeuic4
regardless of the Python version used for compiling PyKDE4, causing
conflicts and possibly installation errors.

This patch fixes the errors by generating first a version-dependent
name (e.g. pykdeuic4-2.7 for Python 2.7) and introducing a parameter
(PYKDE4_ALTINSTALL): if 0 (default), the version dependent name will be
symlinked to a version independent name (e.g. pykdeuic4-2.7 -> pykdeuic4)
otherwise only the version dependent name will be kept.

This is analogous to Python's own "make altinstall" used to provide
coinstallability of different Python versions.

Testing
-------

Tested with both PYKDE_ALTINSTALL=1 and nothing (default: 0).


Thanks,
