Hi Maintainer

As can be seen in reproducible builds [1], aspectc++ FTBFS on arm64
with glibc 2.38.  I've copied what I hope is the relevant part of the
log below.

A bug was filed against glibc [2], but it seems glibc upstream do not
consider it a bug in glibc.

Regards
Graham

Dear maintainers,

glibc 2.38 introduced changes to the bits/math-vector.h file on arm64 in
order to support math vector functions. This unfortunately caused the
FTBFS of your packages.

The change has been temporarily reverted in version 2.38-8 until a fix
is found, and I have opened #1070668 on the glibc side to track the
issue, with a Cc: to the arm64 porters.

I am therefore downgrading the bugs to severity important. However this
should not prevent working on a solution to the problem with the arm64
porters, and depending on the case either at the package level, or at
the upstream glibc/gcc/llvm level.

Regards
Aurelien
