This bug was fixed in the package llvm-toolchain-11 - 1:11.0.1-2ubuntu5
---------------
llvm-toolchain-11 (1:11.0.1-2ubuntu5) impish; urgency=medium
* Fix FTBFS with Linux 5.13 and GCC 11. (LP: #1939424)
- d/p/libsanitizer-remove-cyclades.patch: Fix FTBFS with Linux 5.13,
where the Cyclades TTY code has been removed. For this reason,
libsanitizer's Cyclades support also needs to be removed.
- d/p/fix-missing-include-limit.patch: Fix FTBFS with GCC 11, which now
requires that <limits> be included if the source wants to use
std::numeric_limits.

This is happening because the Cyclades driver has been finally removed
from Linux (after being orphaned 13 years ago):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/include/uapi/linux?h=v5.12&id=f76edd8f7ce06cdff2fe5b6b39a49644c684a161
LLVM includes cyclades.h when building libsanitizer, and therefore the
FTBFS occurs.
Upstream has fixed this by removing support for Cyclades from
libsanitizer:
https://github.com/llvm/llvm-
project/commit/884040db086936107ec81656aa5b4c607235fb9a
As for the GCC 11 failure, the problem is:

/<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.h:17:18: note:
'kmax' declared here
static const T kmax = std::numeric_limits<T>::max();
This comes from the fact that GCC 11 requires the inclusion of the
<limits> header in order to access std::numeric_limits<T>. This has
also been fixed upstream:
https://github.com/llvm/llvm-
project/commit/b498303066a63a203d24f739b2d2e0e56dca70d1
I'm preparing and testing a patch, and will attach it to this bug
soon.
