Actually, it's "make ENABLE_OPTIMIZED=1".  Perhaps it should also allow
ENABLE_RELEASE=1 as a synonym.

Note that if you run ./configure the usual way, you *always* have to run
"make ENABLE_OPTIMIZED=1" to build, and if you ever run just "make" it
will happily do a debug build for you.  Note that the objdir can hold 3
separate build trees for the same source code: Debug, Release, and
Profile, with those subdirectory names.

To make life easier for yourself, run "configure --enable-optimized" and
it will then default to ALWAYS building release mode, assuming you don't
want debug mode at all.

This is documented here:
http://llvm.cs.uiuc.edu/docs/GettingStarted.html#config

Personally, I think --enable-optimized is a strange name, because why
would anyone want to "disable" optimization? :)  Maybe it should be
something like --build-optimized, --build-profile, and --build-debug, or
even --build={opt,prof,debug} since it's a 3-way switch, and you can't
pick and choose more than one of them at a time.
