:>Why not do "make includes" before "make do-tools" for build.sh?

: that strikes me as a bad idea, since you could then end up with
: include files that reference functions that aren't implemented in libc
: yet, for example: __unsetenv13, __sigaction14, ...

That is exactly the reason I was given when I made a similar query
when the toolchain build system was introduced :-)  Your tools need to
build with a matching set of includes & libs.
