"VAX does not fully populate the register move costs table, so do not
access it w/o checks.
Hack to work around PR toolchain/53176."
Will commit a more upstream-friendly variant shortly.

Suppress SIGTTOU when handling errors
Calls to error () can cause SIGTTOU to send gdb to the background.
For example, on an Arm build:
(gdb) b main
Breakpoint 1 at 0x10774: file /build/gdb/testsuite/../../../src/binutils-gdb/gdb/testsuite/gdb.base/watchpoint.c, line 174.
(gdb) r
Starting program: /build/gdb/testsuite/outputs/gdb.base/watchpoint/watchpoint
[1]+ Stopped ../gdb ./outputs/gdb.base/watchpoint/watchpoint
localhost$ fg
../gdb ./outputs/gdb.base/watchpoint/watchpoint
Cannot parse expression `.L1199 4@r4'.
warning: Probes-based dynamic linker interface failed.
Reverting to original interface.
The SIGTTOU is raised whilst inside a syscall during the call to tcdrain.
Fix is to use scoped_ignore_sigttou to ensure SIGTTOU is blocked.
In addition fix include comments - job_control is not included via terminal.h
gdb/ChangeLog:
* event-top.c: Remove include comment.
* inflow.c (class scoped_ignore_sigttou): Move from here...
* inflow.h (class scoped_ignore_sigttou): ...to here.
* ser-unix.c (hardwire_drain_output): Block SIGTTOU during drain.
* top.c: Remove include comment.
When we build netbsd on another OS, we produce a cross compiler without
these definitions.
Fixes some compiler crashes when building netbsd/vax on linux.
- NETBSD_ENABLE_PTHREADS removed (default always)
- HAVE_GNU_INDIRECT_FUNCTION enabled for some platforms
- switch to dragondfly bsd locale routines after christos made them work for us
thread. When attaching to a process that has threads make sure that we
mutate the inferior_ptid (that currently has lwpid == 0 to the first thread
we encounter.
- gdb_assert.h has moved into common/gdb_assert.h.
- force promotion to avoid compile errors
XXX why aren't these files built into the native binary, and
triggered normal build failures.
