libjava broken on the trunk on i386-darwin8.11

[Andrew Pinski]

Hi,
  Sometime between revision 151933 and 152300, libjava is broken on
i386-darwin8.11.
libgij.so fails to build with the following error:
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols:
_libiconv
_libiconv_close
_libiconv_open
_environ
collect2: ld returned 1 exit status

Here was the link line:

from the link line.
