By default, if any of the commands for a target fail then
make will
exit with a non-zero status.  There are a few ways to tell
make to
ignore the exit status of some or all commands (c.f. the GNU
make info
pages, section "5.5 Errors in Commands"). 
Alternatively, the commands
in the makefile may have been written such that they always
return
success.  For example, in this rule:

all:
        $(MAKE) -C subdir all  ||  echo "subdir
failed"

the command invoked won't fail unless both the sub-make
_and_ the 'echo' fail.

If the above isn't sufficient to let you see the problem in
your
makefile, then you'll need to post the rule w/commands that
are
involved from the makefile where the error stops
propagating.
