Fixes to set correct si_code values (such as TRAP_BRKPT) were made to the remaining FreeBSD architectures (MIPS and sparc64) in the head branch leading up to 12.0 and were merged back between the 11.2 and 11.3 releases. gdb/ChangeLog: * fbsd-nat.h: Include <osreldate.h>. Define USE_SIGTRAP_SIGINFO for all architectures on FreeBSD 11.3 and later.
