If I am following correctly:

The assembler we test for features in Gunther's case has always been
$prefix/bin/as - luckily harmless for him and he probably never
noticed.  The installed compiler uses $prefix/$target/bin/as. The
being-built compiler has switched from one to the other.

One appropriate default for --with-build-tools could be the same as
the defaults for --program-transform-name.  A default native build
would use 'as', a default cross build would use '$target-as'.  Most
people using --program-prefix would probably also pass the same value
to --with-build-tools.
