That's a false statement.  Since you can't reproduce this without
first having the system's headers, it's not from virgin sources.

In any case, your procedure is no easier than running a properly written
(real) virgin source build procedure, and is indeed impossible
for platforms where there are no headers already built to steal.

I should mention that I tried using a procedure like yours
for a while, but it bit me on the behind when I tried to
move up to a newer compiler.  I gave up on trying to keep
it working, and have shifted my efforts to a totally reproducible
clean build from virgin gnu sources.  Once I have my scripts
finished, it'll be very, very easy to create a truly clean
cross toolchain.  Even you might agree it'll be easier than
the procedure you have so often and vigorously proposed.
