#114 jimtcl: Static Analyzer build outside of source tree.

[Rick]

When configuring and building outside the source tree with clang static analyzer, jim-config.h header file not found.

Makefile.in adds flags, and a require header path, to CC and CXX. Static analyzer re-writes these, and the flags are not applied. The missing include path does not pick up the jim-config.h in the build directory.
