Confusing instructions for building LLVM?

[ernest.prabhakar@…]

In the README:

 https://www.macruby.org/trac/browser/MacRuby/trunk/README.rdoc

It gives one command for the "normal" build:

$ env UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" CC=/usr/bin/gcc CXX=/usr/bin/g++ make

and a rather different one for the optimized build:

$ UNIVERSAL=1 UNIVERSAL_ARCH="i386 x86_64" ENABLE_OPTIMIZED=1 make -j2

i.e., the "env" command and "ENABLE_OPTIMIZED=1". Is there a reason for them to be different, or is that just historical baggage?

Fixed in r4107.
