First, my newest patch was sent on July 4 and was definitely working.
If you apply the patch 3 days later, I don't see how I can prevent  
other patches from breaking it.

Second, here are some further info about why this patch is needed:
To cross compile on Mac OS X, you need to pass -isysroot when  
compiling *AND* when linking.

The issue is that is you pass it to both --extra-ldflags and --extra- 
cflags gcc will complain whenever both CFLAGS and LDFLAGS are passed  
at the same time (like in configure). That's why I added a --extra- 
commong-flags which can be used for flags required for both and which  
cannot be duplicated on the command line.

This is really helpful to cross compile and then generate an  
universal binary with lipo.

Please let me know if I should spend some time to update the patch,  
or if you will reject it anyway.
