Use SRCDIR as a working directory
The existing behavior of using the build directory as the working directory is useful if you want to move/copy the output directory around and SRCDIR still refers the the source. But, it's more useful to have the source directory be the working directory. Tools like cpp(__FILE__) and other debug prints embed relative paths from the working directory. We also have tools that expect the working directory to be $TOP. Change-Id: Ia0f1d3c6b7df72d61cf5628efa2baa98bd19775b
