2 problems were found, but are in one change to avoid submitting a patch
that might fail to build. The problems were:
1. The macro MAKE_PREREQ_DIR has a minor bug, in that it is capable of
generating recursive dependencies.
2. The inclusion of BUILD_DIR in TEMP_OBJ_DIRS left no explicit
dependency, BUILD_DIR might not exist when subdirectories are
created by a thread on another CPU.
This fix corrects these with the following changes:
1. MAKE_PREREQ_DIR does nothing for a direct self dependency.
2. BUILD_DIR is built using MAKE_PREREQ_DIR.
3. BUILD_DIR is an explicit prerequisite of all OBJ_DIRS.
