Use abspath to dereference $BUILD_BASE
If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.
This patch also adds documentation that BUILD_BASE can be specified by
the user.
