tests/tcg: better detect confused gdb which can't connect

Browse Source 
While we may gamely give the right information it can still confuse
the wide range of GDBs out there. For example ppc64abi32-linux-user
reports:

  warning: Selected architecture powerpc:common is not compatible with reported target architecture powerpc:common64
  warning: Architecture rejected target-supplied description

but still connects. Add a test for a 0 pc and exit early if that is
the case. This may actually be a bug we need to fix?
