Don't include sigtramp or foocontext routines in rumprun mode. They won't
...
work (since a rump kernel does not provide NetBSD _lwp syscalls nor
signals), but they cause unwanted symbols to be pulled in when the
resulting libc is linked.

Replace the branch to __cerror() in powerpc64 syscall stubs
...
with inline code which does what __cerror() was doing. #ifdef
that code (i.e. all code) out of cerror.S; __cerror() is no more.
This seems to be necessary to fix the link of rescue/rescue, and
should have the pleasant side effect of making all other workarounds
done to keep the 'b __cerror' working unnecessary.

The OpenRISC calling standard only passes 6 parameters by register. Any
...
others are passed on the stack. NetBSD syscalls use up to 8 parameters
so that could mean two left on the stack for the kernel to access. It's
easier for the kernel if userland could fetch into registers beforehand.
So we generate sysassym.h which contains the number of arguments for each
syscall and then use that to determine how many arguments need to be fetched
from the stack.

This fixes a segmentation fault caused by bash 4.3 on sparc64

option (and define __sparc_v9__), use a similar code to 64-bit
library.
