Within a new environment, "make setup" will fail if it expects to use the tools
from usr/src/tools. The first target calls for building dynamic mapfiles, which
required "cw", which hasn't been built yet:
% make setup
<env>/usr/src/common/mapfiles
<env>/usr/src/common/mapfiles/gen
<env>/usr/src/tools/proto/opt/onbld/bin/i386/cw -_cc -O -xspace -Xa \
-xildoff -errtags=yes -errwarn=%all -erroff=E_EMPTY_TRANSLATION_UNIT \
-erroff=E_STATEMENT_NOT_REACHED -xc99=%none -W0,-xglobalstatic -DTEXT_DOMAIN=\"\" \
-D_TS_ERRNO -I/local/ws/onnv-l-direct-setup/proto/root_i386/usr/include -o main.1 \
-Mmap.noexeglobs.1.template main.c
sh: <env>/usr/src/tools/proto/opt/onbld/bin/i386/cw: not found
At first it looks like a catch-22, as some of the tools required mapfiles. However,
the tools only use the constant mapfiles from usr/src/mapfiles, not the dynamic
mapfiles that must be built. (The tools realy don't need mapfiles at all, as all
our mapfiles provide optimizations in regards object layout etc., that are only
required by those objects we deliver with the product. However, the tools can
be deposited under $ROOT, and then check_rtime() will complain that they haven't
been built appropriately, so we use the mapfiles to keep this build potential quiet).
