Building gcc on Ubuntu 11.10

[Nenad Vukicevic]

Has anybody tried to build 4.7 on Ubuntu 11.10 system. I am getting the
following linking problem (no special configure switches):
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: cannot find -lgcc
/usr/bin/ld: cannot find -lgcc_s

Noramly they under /usr/lib64, but 11.10 has them under 
/usr/lib/x86_64-linux-gnu.

Thanks,
Nenad
