dev-util/cmake: Bump cmake with my lib32 patch to cmake-2.8.3-r1, following gentoo-x86's changes.

(Portage version: 2.2.0_alpha11-r1/hg/Linux x86_64, signed Manifest commit with key 6BA81050)

dev-util/cmake: Drop cmake-2.6.4-r3 as official portage tree dropped cmake-2.6.

(Portage version: 2.2.0_alpha12/hg/Linux i686, unsigned Manifest commit)

Actually enable the FIND_LIBRARY_USE_LIB32_PATHS cmake property by default in my patch... somehow I left it disabled by default which doesn't help fixing compilation problems ;-).

dev-util/cmake: Update the FIND_LIBRARY_USE_LIB32_PATHS patch to mostly match the version I pushed upstream. Also fix CVS header for cmake-2.8.1-r2.

dev-util/cmake: Add a patch to cmake which enables kde-base/kdelibs to compile on systems where /usr/lib is neither a symlink to /usr/lib64 or /usr/lib32. This adds a FIND_LIBRARY_USE_LIB32_PATHS global property which is an analog to the FIND_LIBRARY_USE_LIB64_PATHS property.
