Each architecture overrides the struct msqid_ds which its required
kernel ABI one.
Checked on x86_64-linux-gnu and some bases sysvipc tests on hppa,
mips, mipsle, mips64, mips64le, sparc64, sparcv9, powerpc64le,
powerpc64, and powerpc.

Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '
s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure

After my patch to move SHMLBA to its own header, the bits/shm.h
headers for architectures using the Linux kernel still vary in a few
ways: the use of __syscall_ulong_t; whether padding for 32-bit systems
is present before or after time fields, or missing altogether (mips,
x32); whether shm_segsz is before or after the time fields; whether,
if after time fields, there is extra padding before shm_segsz.
This patch arranges for a single header to be used. __syscall_ulong_t
is safe to use everywhere, while bits/shm-pad.h is added with new
macros __SHM_PAD_AFTER_TIME, __SHM_PAD_BEFORE_TIME,
__SHM_SEGSZ_AFTER_TIME and __SHM_PAD_BETWEEN_TIME_AND_SEGSZ to
describe the differences.
Tested for x86_64 and x86, and with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add
bits/shm-pad.h.
* sysdeps/unix/sysv/linux/bits/shm.h: Include <bits/shm-pad.h>.
(shmatt_t): Define as __syscall_ulong_t.
(__SHM_PAD_TIME): New macro, depending on [__SHM_PAD_BEFORE_TIME]
and [__SHM_PAD_AFTER_TIME].
(struct shmid_ds): Define time fields using __SHM_PAD_TIME.
Define shm_segsz and associated padding based on
[__SHM_SEGSZ_AFTER_TIME] and [__SHM_PAD_BETWEEN_TIME_AND_SEGSZ].
Use __syscall_ulong_t instead of unsigned long int.
[__USE_MISC] (struct shminfo): Use __syscall_ulong_t instead of
unsigned long int.
[__USE_MISC] (struct shm_info): Likewise.
* sysdeps/unix/sysv/linux/bits/shm-pad.h: New file.
* sysdeps/unix/sysv/linux/hppa/bits/shm-pad.h: Likewise.
