The top level configury suggests that you can simply drop gmp, ppl, etc
into the top level source dir and they will get configured and used.
Does this really work?
At the very least, I think ppl requires that gmp be configured with
--enable-cxx, like so:

host_modules= { module= gawk; };
host_modules= { module= gettext; };
host_modules= { module= gmp; lib_path=.libs; bootstrap=true;

+ extra_configure_flags='--disable-shared --enable-cxx';
no_install= true;
host="none-${host_vendor}-${host_os}";
target="none-${host_vendor}-${host_os}"; };
Even then, the ppl configury isn't detecting the gmp we just built. It
seems as though we should install gmp in a local temporary install tree
and point ppl at that. See below for a trace of the ppl configury as it
attempts to detect an in-tree gmp (after applying the patch above).
