In looking over suspended PRs, I found this one. It's about our build 
system not updating the local environment to have all the tools 
needed to do the build. I agree that the build system should not do 
that (think "cross-compiles"), but we could go half-way: *check* the 
local environment to see if all the tools are there at the outset 
(e.g. make_cmds & compile_et for Kerberos) so that you don't waste 
half a day on an old m68k machine doing a build that fails.

The information is already in the build scripts (don't we have a 
variable for each command executed, e.g. YACC, CC, LD, STRIP, etc), 
so it shouldn't be too difficult to construct a check.
