I think this (libc++1) applies to source package 'llvm-defaults'.

Title:
[UBUNTU 24.04] Exception handling support is disabled in
libc++/libc++abi

Bug description:
Currently the C++ exception handling support is disabled for s390x
when building libc++/libc++abi packages:
ifneq (,$(filter $(DEB_HOST_ARCH),s390x))
STAGE_ALL_CMAKE_EXTRA += -DLLVM_HOST_TRIPLE=s390x-linux-gnu
LIBCXX_EXCEPTIONS := OFF
However, this is supposed to work on s390x and has already been
enabled in other distros. Please, remove the s390x special handling
here.
Be aware that we used to lack proper libunwind support for Z, what
might have triggered this. But this has been solved some time ago.

Ubuntu package:
libc++abi1-18 1:18.1.3-1ubuntu1
---------------------------------------------------
libunwind could be enabled for s390x as well:
# Enable libunwind (or not)
LIBUNWIND_ENABLE=yes
ifneq (,$(filter $(DEB_HOST_ARCH), s390x armel m68k mipsel mips64el hurd-i386
powerpc sparc sparc64 x32))
LIBUNWIND_ENABLE=no
