The machine the code will run on is the "host".  Since libstdc++ runs
on the thing the toplevel knows as "target", it follows that for
compiling libstdc++ the toplevel must set host to target.  "target" is
the machine that code will be compiled for, but libstdc++ isn't
a compiler, so it doesn't need a target setting.
