So no, I think.

I then installed GNU libsigsegv 2.12, reran configure, and `make`, then `make 
check` passed!

# ./test-c-stack
test-c-stack: stack overflow

# uname -srm
Linux 5.9.6-gentoo sparc

I’ll see about getting a newer kernel.

I’m using glibc (glibc-2.32-r6) which is 2.32 with some backports applied [0].

# file test-c-stack
test-c-stack: ELF 64-bit MSB pie executable, SPARC V9, relaxed memory ordering, 
version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux.so.2, for 
GNU/Linux 3.2.0, with debug_info, not stripped
