By "normal builds", I will mean non-world, non-cross ones like
"cd somwhere; make" :-).

I think he actually wanted it for normal builds like
"cd /usr/src/gnu/usr.bin/cc; make". Then $PATH is just the user's path
and "." might/should not be in it.
Your changes seem to be more or less correct. build-tools seems to
have depended on using the wrong MACHINE_ARCH in TMAKEENV to build the
tools in a bogus place where they "accidentally" prevented harmful
rebuilding in stage 4. But this hack only worked for the tools binaries
at best. Any use of the binaries in stage 2 or 3 may have left
non-binaries in a bogus place where they accidentally prevented required
building in stage 4. You fixed this for cc and f77 tools but there
may be problems with others. It's not clear that tools binaries built
in stage 2 or 3 will work with a different MACHINE_ARCH in stage 4, but
cross-tools should.
Not Marcel
