src/sys/arch/aarch64/include: signal.h
Log Message:
Normally, to support COMPAT_NETBSD32 we need to define
__HAVE_STRUCT_SIGCONTEXT in order to support the old
"sigcontext" style of handlers for 32-bit binaries.
However, we only support 32-bit EABI binaries on AArch64,
and by happy accident (due to a libc bug introduced in
2006), 32-bit NetBSD EABI binaries never used "sigcontext"
style handlers. So, we don't need to carry any of this
baggage forward.
This addresses the AArch64 case of PR kern/56487.
