* sysdeps/mach/Makefile (mach-before-compile rule): Pass generating=t, use target mach-before-compile instead of generated. (mach-before-compile): New target. * Makerules: Disable use of tls.make if $(generating) is set. * mach/Makefile: Include mach-syscalls.mk even if no_deps=t. * sysdeps/mach/hurd/Makefile: Make generated hurd headers depend on mach-shortcuts.h so mach/ generation happens before hurd/.
