[Bug bootstrap/21744] New: Internal compiler error during build

["sebastient at otii dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Trying to build m6812 cross compiler causes an internal compiler error.  Configured with ../../
gcc-4.0.0/configure --prefix=/usr/cross/m6812 --target=m6812 (using the gcc-core-4.0.0, using 
only the c compiler).  Re-running the command that failed with a -v causes the following error..
