Subject: [PATCH] With CLANG_ENABLE_STATIC_ANALYZER=0, link clang properly and
 skip clang-check.

Previously, the CMake build still tried to link clang against the static
analyzer libraries, even if CLANG_ENABLE_STATIC_ANALYZER was off.
Furthermore, clang-check depends on the analyzer, so it should be disabled
(in both CMake and configure builds).

In theory, clang-check could be made to conditionally include analyzer
support (like clang itself), but for now this at least gets a CMake ALL_BUILD
working.

Patch by Stephen Kelly, modified by me.
