Tobias Klauser 530d0810a4 unix: add utimensat libc wrapper on darwin 
Direct syscalls are no longer supported on darwin (CL 250437), so
utimensat can be implemented as a wrapper around the libc function.
The utimensat function was added in macOS 10.13 and Go 1.17 dropped
support for macOS 10.12.

This also allows to drop the fallback to setattrlistTimes which was
used to set timestamps with nanosecond resolution before utimensat could
be used, see golang/go#22528 and CL 74952.

Kir Kolyshkin 0005352912 unix: Getwd: ensure returned path is absolute 
Since Linux kernel 2.6.36, the pathname returned by the getcwd() system
call can be prefixed with the string "(unreachable)" in some cases [1].

Getcwd should return an absolute path, and doing otherwise is a
conformance issue; it also can be dangerous, since the path returned
can be an existing relative path.

Fix by returning ENOENT in case the path is not absolute. This is
essentially the same as what glibc does (since [2]).

SYS_ALARM is not defined for arm* or riscv, but is available for all other

In order to handle special case files such as this one (which don't match the
existing syscall_linux_goarch.go scheme), I've added logic to the Linux build
system which can evaluate the build constraints in a given file to determine
whether that file should be appended to the arguments for a given target.

The pipe2 syscall is part of NetBSD since version 6.0 and thus exists in
all officially supported versions (6.0 through 6.1 and 7.0+).

Follows CL 94035 which did the same for package syscall.

Russ Cox 798191bca9 unix, plan9: avoid writing to p when Pipe(p) fails 
Generally speaking Go functions make no guarantees
about what has happened to result parameters on error,
and Pipe is no exception: callers should avoid looking at
p if Pipe returns an error.

However, we had a bug in which ForkExec was using the
content of p after a failed Pipe, and others may too.
As a robustness fix, make Pipe avoid writing to p on failure.

windows.Pipe already avoided writing to p on failure.

For golang/go#50057.

Johan Jansson 7580c6e521 unix: factor out mkmerge into a proper package 
Factor mkmerge.go and mkmerge_test.go into package internal/mkmerge.

Due to ignore constraints, mkmerge_test.go wasn't run by the Go
builders and failing tests were unnoticed.

Factoring mkmerge into its own package and removing ignore constraints
makes the tests run automatically by the Go builders.

Johan Jansson 7c45f0c2c7 unix: mount Docker-based builder at x/sys 
Mount the data volume for the Docker-based builder at x/sys instead of
x/sys/unix.

The x/sys/go.mod file was not included in the data volume when mounting
x/sys/unix. This breaks module-aware go commands that run within the
Docker container.

Fix this problem by mounting the volume at x/sys and updating the
working directory of the builder accordingly.
