XFAILs at the Makefile level for the signal.h and sys/wait.h tests for
most standards weren't removed until August 2017 (commit
4fa9b3bfe6759c82beb4b043a54a3598ca467289, once the ucontext.h namespace
fixes were completed), after the accidental SPARC si_band change, and so
served to hide that architecture-specific problem.
