Yes - I have seen this approach on-line, as well as the approach used in
LinuxFromScratch.  It was confusing, in part as I could find no
documentation about the "all-gcc" target, and also as there seemed to be
two ways in the same build system to do the same thing (and indeed, this
does seem to be so).
