# Install rules. Each build config is classified as "primary" (the first
# config for an architecture) or "non-primary". Primary build configs
# have the semantic of competing to *combine* single-architecture
# files into a multi-architecture output in the DSTROOT, like
# $(DSTROOT)/$(KERNEL_FILE_NAME), and consequently each primary build config
# has its install target run serially with respect to other primary
# build configs. Non-primary build configs will never compete for
# files in the DSTROOT or SYMROOT, and can be installed in parallel
# with other non-primary configs (and even primary configs)
