This fixes parts of gdb.arch to be parallel-safe. I only changed the bits I could test on this machine. I don't have access to many of the machines needed to fully switch gdb.arch; but I am happy to provide advice to others attempting this. Or, I can send an untested patch to convert it all. Tested on x86-64 Fedora 18. * gdb.arch/amd64-byte.exp: Use standard_testfile, clean_restart. * gdb.arch/amd64-disp-step.exp: Use standard_testfile. * gdb.arch/amd64-dword.exp: Use standard_testfile, clean_restart. * gdb.arch/amd64-entry-value-param.exp: Use standard_testfile. * gdb.arch/amd64-entry-value.exp: Use standard_testfile. * gdb.arch/amd64-prologue-xmm.exp: Use standard_testfile. * gdb.arch/amd64-word.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-avx.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-byte.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-disp-step.exp: Use standard_testfile. * gdb.arch/i386-dr3-watch.exp: Use standard_testfile. * gdb.arch/i386-permbkpt.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-signal.exp: Use standard_testfile. * gdb.arch/i386-size-overlap.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-sse.exp: Use standard_testfile, clean_restart. * gdb.arch/i386-unwind.exp: Use standard_testfile. * gdb.arch/i386-word.exp: Use standard_testfile, clean_restart.
