The following test cases were previously skipped on sparc with the
message "PTRACE_ILLEGAL_ASM not defined", but now they fail instead:

This changed during the period of build breakage that started with

  2019.04.16.11.38.21 martin src/sys/arch/sparc/include/ptrace.h 1.12

and ended with

  2019.04.17.15.42.02 martin src/sys/arch/sparc/include/ptrace.h 1.13

Log output from the first failure is at:
