In Fedora 15, with clang 2.8, 'scan-build env' shows:
CCC_ANALYZER_ANALYSIS=-analyzer-check-objc-mem -analyzer-check-security-syntactic -analyzer-check-dead-stores -analyzer-check-objc-unused-ivars -analyzer-check-objc-methodsigs
But in rawhide, with clang 2.9, the same variable is set but
empty, implying the default set of analysis. We still want
sa_assert defined in that case, to stop clang from hitting
false positives.
* configure.ac (STATIC_ANALYSIS): Detect clang even when the set
of analyses is the default.

I'm pushing this under the trivial rule. It has no effect on
a real build, but makes it easier for me to repeat my clang
testing on rawhide.
