 # - any arch listed in ARCHES (see below)
 # - any mode listed in MODES
 # - every combination <arch>.<mode>, e.g. "ia32.release"
+# - "native": current host's architecture, release mode
 # - any of the above with .check appended, e.g. "ia32.release.check"
 # - default (no target specified): build all ARCHES and MODES
 # - "check": build all targets and run all tests
