ld: Undefined symbols:

make[3]: *** [libjavalang.la] Error 1

There are 3 problems here:

1. duplication of symbol sqrt (in libSystem.dylib) - check #ifdef __MATH__
2. can't find symbol environ
3. target library name is wrong - should be .libs/libjavalang.0.0.0.dylib

OK, this is now fixed in libffi.
