[Bug boehm-gc/34728] New: Unrecognized opcode: `lwsync' when compiling gcc 4.2.2 on a 7457

["tom at software6 dot net" <gcc-bugzilla at gcc dot gnu dot org>]

This is Yellowdog 3 and Linux 2.4. I've previously built and installed gcc
4.1.1 which has worked well for years. But I've recently had a need to build
and install gdb 6.7.1. But that had problems building (the details now
forgotten). And so as a stab in the dark I am now trying to build and install
gcc 4.2.2 so I can build and install gdb 6.7.1. This means that gcc 4.2.2 has
been compiled with gcc 4.1.1 in stage 1. The "native" version of gcc is 3.2.2.
