This fixes the failing test add-to-entropy-count in tests/syscalls.scm on
powerpc64le-linux.
* guix/build/syscalls.scm (RNDADDTOENTCNT): When %host-type starts with
"powerpc64le", set this to #x80045201. Otherwise, set it to #x40045201 as
before.
This makes the clone procedure work correctly and fixes some test failures on
powerpc64le-linux, including tests/containers.scm.
* guix/build/syscalls.scm (clone): Add an entry for ppc64le.
On some systems, the columns in /proc/self/mountinfo look like this:
23 28 0:21 / /proc rw,nosuid,nodev,noexec,relatime shared:11 - proc proc rw
Before this change, the mounts procedure was written with the assumption that
the type and source could always be found in columns 8 and 9, respectively.
However, the proc(5) man page explains that there can be zero or more optional
fields starting at column 7 (e.g., "shared:11" above), so this assumption is
false in some situations.
* guix/build/syscalls.scm (mounts): Update the match pattern to use ellipsis
to match zero or more optional fields followed by a single hyphen. Remove the
trailing ellipsis, since multiple ellipses are not allowed in the same level.
The proc(5) man page indicates that there are no additional columns, so it is
probably OK to match an exact number of columns at the end like this.
* guix/build/syscalls.scm (<mount>): New record type.
(option-string->mount-flags, mount-flags)
(octal-decode, mounts): New procedures.
(mount-points): Rewrite in terms of 'mount'.
* tests/syscalls.scm ("mounts"): New test.
Avoid crash

Reported by Jan (janneke) Nieuwenhuizen <janneke@gnu.org>.
Before that, we'd always use the 'sizeof' and 'alignof' value obtained
from the host at macro-expansion time.
* guix/build/syscalls.scm (sizeof*, alignof*): When the target word size
differs from the host word size, emit a call to 'sizeof'/'alignof'.
Partly fixes <https://bugs.gnu.org/40574>.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.
Previously, we'd choose at expansion time whether to use the Hurd or the
Linux variant, taking the cross-compilation target into account. This
would lead to the wrong decision when (guix build syscalls) is evaluated
while we're cross-compiling to GNU/Hurd.
This is a followup to 1ab9e48339.

This new procedure uses BLKRRPART to determine whether or not a device is
busy. It is useful when a device does not appear as mounted but is maybe used
by the kernel. This is the case with overlayfs lowerdir backend device for
example.
