Subject: [PATCH] [Arm][libsanitizer] Fix arm libsanitizer failure with
 bleeding edge glibc

Glibc has recently introduced changed to the mode field in ipc_perm in commit
2f959dfe849e0646e27403f2e4091536496ac0f0. For Arm this means that the mode
field no longer has the same size.

This causes an assert failure against libsanitizer's internal copy of ipc_perm.
Since this change can't be easily detected I am adding arm to the list of
targets that are excluded from this check.

Subject: [PATCH] Fix sanitizer-common build with glibc 2.31

Summary:
As mentioned in D69104, glibc changed ABI recently with the [[ 
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=2f959dfe849e0646e27403f2e4091536496ac0f0|
 2f959dfe ]] change.
D69104 dealt with just 32-bit ARM, but that is just one of the many affected 
architectures.
E.g. x86_64, i?86, riscv64, sparc 32-bit, s390 31-bit are affected too (and 
various others).

This patch instead of adding a long list of further architectures that wouldn't 
be checked ever next to arm 32-bit changes the structures to match the 2.31 
layout and performs the checking on Linux for ipc_perm mode position/size only 
on non-Linux or on Linux with glibc 2.31 or later.  I think this matches what 
is done for aarch64 already.
If needed, we could list architectures that haven't changed ABI (e.g. powerpc), 
so that they would be checked even with older glibcs.  AFAIK sanitizers don't 
actually use ipc_perm.mode and
so all they care about is the size and alignment of the whole structure.

Note, s390 31-bit and arm 32-bit big-endian changed ABI even further, there 
will now be shmctl with old symbol version and shmctl@@GLIBC_2.31 which will be 
incompatible.  I'm afraid this isn't really solvable unless the sanitizer 
libraries are symbol versioned and use matching symbol versions to glibc 
symbols for stuff they intercept, plus use dlvsym.
This patch doesn't try to address that.
