This broke the build on old versions of the OS because sys/sysctl.h isn't installed to WORLDTMP before bootstrap-tools:

 231 # 1. legacy stage [BMAKE]
 232 #       This stage is responsible for creating compatibility
 233 #       shims that are needed by the bootstrap-tools,
 234 #       build-tools and cross-tools stages. These are generally
 235 #       APIs that tools from one of those three stages need to
 236 #       build that aren't present on the host.
 237 # 1. bootstrap-tools stage [BMAKE]
 238 #       This stage is responsible for creating programs that
 239 #       are needed for backward compatibility reasons. They
 240 #       are not built as cross-tools.
