Getting Makefile to show command that was run

[Arch Robison]

I'm working on getting the new GC into the threading branch, and am at the point where the code compiles but crashes (progress!).  How do I get the build process to show me what command it was running, so I can replay it in a debugger?  Here's the point in the build where I want to debug whatever "JULIA..." is doing.

$ make
fatal: bad revision '^upstream/master'
fatal: Not a valid object name upstream/master

I believe `make VERBOSE=1` will help?
