I should interject that I've already added code to Makefile.inc1 in 7, 8
and 9 so yacc is a bootstrap tool when building on a system that has
byacc, so right now Baptiste's proposed change won't make much
difference, but we should definitely give some thought to what we
consider a bootstrap tool and when we should build them.  Blindly
removing all conditionals is *not* an option, though, as some of the
bootstrap tools take ages to build.  Remember that all bootstrap tools
and build tools are built twice, once during the bootstrap / toolchain
phase and once during the everything phase.
