breakpoints/13457 discusses issues with syscall catchpoints when following forks, lamenting that there is no coverage for the various permutations of `follow-fork-mode' and `detach-on-fork'. This is an attempt to try and cover some of this ground. Unfortunately the state of syscall support when detaching after the fork is very, very inconsistent across various architectures. [I've tested extensively Fedora/RHEL platforms.] Right now, the only reliable platform to run tests on is x86_64/i?86 for the specific case where we do not detach from the fork. Consequently, this patch limits testing to those architectures. I have updated breakpoints/13457 with my findings on failures with the detaching case.
