I've changed `configure' so that it correctly finds `strip' based on
--host, and `strip' is now used by default for an install.


Looking at your script (and the original one for Android), I note that
you could simplify it by configuring with
`--enable-racket=$BUILD_HOST/src/racket/racket3m' and dropping the
`RUN_THIS_RACKET...=' arguments to `make'.

Also, the HOSTCC stuff is needed only by the Boehm collector, so using
`--enable-sgc' would simpler. I've added a note along those lines to
"src/README".
