unable to bootstrap gcc 4.7.0

[Jim McKim]

Possibly an issue with gcc multilib support.

Stage 1 gcc (using the native Ubuntu gcc to compile the gcc 4.7.0 source) won't build unless the gcc-multilib package is installed.

After installation of the package, the stage 1 gcc does build successfully. That stage 1 gcc, however, is unable to link an executable (e.g. when it tries to compile itself in stage 2), failing with the diagnostic:

"/usr/bin/ld: cannot find crti.o: No such file or directory"

The default configuration (i.e. no options specified) was used when configuring the gcc 4.7.0 build.
