# Install the binary distribution BUILD staged.  Hadrian has an `install'
# target, but it re-enters the build system, and INSTALL runs in a separate
# delve process that does not see BUILD's variables -- any disagreement over
# the flavour would rebuild the whole compiler.  This is what that target does
# anyway.  Needs GNU make, as in BUILD.
