clang --profile requires nonexistent file on Amazon Linux 2

Hello- when using the al2-provided clang/llvm suite, the --coverage flag fails, claiming there is an archive missing:

[ec2-user@ip-172-31-36-41 ~]$ echo "int main() { }" >| hello.c
[ec2-user@ip-172-31-36-41 ~]$ clang -v --coverage hello.c -o hello

as far as i can tell, that file should be provided by clang/llvm/compiler-rt, but it is not to be found in any of the packages available in the default installation:

[ec2-user@ip-172-31-36-41 ~]$ yum whatprovides /usr/lib64/clang/11.1.0/lib/linux/libclang_rt.profile-aarch64.a
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
222 packages excluded due to repository priority protections
No matches found

this is a stock AL2 image on which i've only run yum groupinstall -y 'Development Tools' ; yum install -y clang-devel llvm-devel

for reference, this works fine in AL2023:

[ec2-user@ip-172-31-27-140 ~]$ clang -v --coverage ./hello.c -o hello

am i missing something here? as far as i can tell, it seems like these should be part of the compiler-rt package, but they're not inlcuded there, and that also seems to be a separate build from the llvm package. i've only dug in a little bit here, though.

it'd be great if we didn't have to go on a toolchain-rebuilding expedition on amazon linux 2, which we'll be using for the duration of its supported life.
