104d4017fa unix: add riscv_hwprobe for riscv64 
The riscv_hwprobe system call was introduced in Linux 6.4 and allows
the caller to determine a number of interesting pieces of information
about the underlying RISC-V CPUs, e.g., which extensions they support
and whether they allow fast unaligned memory accesses.  For more information
please see:

https://docs.kernel.org/riscv/hwprobe.html

We also update linux/mksysnum.go to ensure that the generated syscall constants
written to the zsysnum_linux_*.go files are always sorted by their syscall numbers
in ascending order.

Updates golang/go#61416

25d0004552 unix: fix last argument of pselect6 on linux 
On Linux, the last argument of pselect6 system call is **not** a
sigseg_t * pointer, but instead it is a structure of the form:

    struct {
        const sigset_t *ss;     /* Pointer to signal set */
        size_t          ss_len; /* Size (in bytes) of object pointed
    };

See man 2 pselect6.

Fixes #61251

7a75290698 unix/linux: update to glibc 2.36 
Support for LoongArch has been merged upstream. This allows to
drop the loong64 specific glibc patches.

Because the header file sys/mount.h of glibc 2.36 includes fcntl.h
(commit 78a408ee7ba041fc8d5dbd5f67065b4a982c11e5), this will leads to
duplicate definition of structure stat on MIPS64.  In order to solve
this error, use the custom type my_stat to generate the Go Stat_t.

3681064d51 unix: implement getitimer(2) and setitimer(2) on Linux 
Wrap the low-level system calls with a more idiomatic Go API and a set of
constants to indicate which timer should be queried or modified.

man 2 getitimer indicates that these system calls are obsolete as of
POSIX.1-2008, but the code I am working on has not been ported to the modern
timer_gettime(2) and timer_settime(2) APIs as of yet.

5739886226 unix: implement alarm(2) on Linux on all GOARCH except arm* and riscv. 
SYS_ALARM is not defined for arm* or riscv, but is available for all other
Linux GOARCH values. Ian suggested I create a new file with build tags
matching these constraints.

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.

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.

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.
