Reapply "Add support for product-specific build flags"
1. release config maps now specify where the flag definitions are found.
2. PRODUCT_RELEASE_CONFIG_MAPS specifies additional release config map
files to use.
This allows product config to specify build flags, which can then be
specified by users of that product.
