autogen: add shortcut for running scan-build
scan-build is a static analyzer in llvm. As ususal static analyzers
tend to mostly find theoretical bugs in software that has been in
production for a while. For in-development code it can be useful to
check if new issues is added as there is a chance to spot real problems
before release. For systemd we are now down to 297 issues - the vast
majority are false positives because the tool does not understand the
cleanup attribute.
Running clang's static analyzer scan-build is a bit messy. You have to
run both configure and make "inside" the build-scan tool. To have an
easy shortcut from autogen.sh I thus call both directly from it. This
makes it different from the other options in autogen.sh. I chose 's'
for static analysis.
scan-build is in the package clang-analyzer on fedora.
