This is a first-step hack to have non-default build systems ignore
global options which are related to the build system in use (e.g.
compile or make flags, install/uninstall options, etc.).
This should fix bug 331654 (now that I understand it better) and improve
the situation for bug 332789 (which would be the long-term fix when
implemented).
BUG:331654
CCBUG:332789
FIXED-IN:1.16
This patch does three things:
1-Adds --install-only for the sake of consistency
2-Adds --install into the usage
3-Makes the CMake (KDE4) build system use make install/fast.
make install/fast only performs the installation of the files
thus avoiding a double compilation.

This can be used as a run-time check later to ensure that kdesrc-build
finds compatible versions of its component modules (though that isn't
done yet).
