It's not seeing the 'fi' because it's trying to pass 'fi' as an
argument to 'fail'. You need to end the 'fail' command with a
semicolon.
Eg:
if [ ... ]; then fail; fi

If you wanted to do if/then/else, it would be:

if [ ... ]; then foo; else bar; fi

Also, is there a reason you want to check against a particular return
value? Most commands return 0 on success, and anything else is a
failure. If you just want to stop make on a failure, it becomes quite
a bit easier to do if you follow that trend.
