I now switched back to --disable-lto as I could not resolve the problems that
appear to be a collect2 issue, see
http://gcc.gnu.org/ml/gcc-help/2011-12/msg00016.html
What I can do is:
* build the compiler with the patch and with LTO enabled and without
getting a linker error for c_addr_space_name.
* I cannot get usable results from testsuite because of collect2 breakage
* Testsuite passes fine with the patch and --disable-lto [...]
Ok for trunk?
