Fix errors being ignored in many phases of the build since the bmake integration.

Say it with me, "I will not chain commands with && in Makefiles"

This was originally fixed and explained quite well by bde@ in r36074.  The
initial bmake integration caused 'set -e' to stop being used which lead to
r252419.  Later 'set -e' expectations were fixed with bmake in r254980.

Because of the && here, errors would be ignored when building in parallel and
a dependency failed.  Such as bootstrap-tools since it builds everything in
parallel.  If any tool failed in obj/depend/all, it would just ignore the error
and continue to build.  This later would result in cascaded errors that only
confused the real issue.  This could also cause commands after the failed
command to still execute, leading to more confusion.

This should be fine if the command is in a sub-shell such as: (cmd1 && cmd2)

This reverts r252419.
