I would rather not change -l. This option saves a ton of space when 
copying openjdk to openjdk-ecj. The only files that are actually 
written, are those that differ between openjdk and openjdk-ecj. All the 
rest remained linked.

I am quite surprised OS X does not support this. Maybe just patch it 
out, it will have no side-effects other than loss of disk space.
