In file included from src/timeout.c:53:0:
/gnu/store/4fy2658sxphy1kgclxrrmcka6lwiwap0-glibc-bootstrap-0/include/sys/prctl.h:22:66:
 fatal error: linux/prctl.h: No such file or directory
 #include <linux/prctl.h>  /*  The magic values come from here  */

I'm not sure if it's because armhf and aarch64 are using
%bootstrap-glibc vs glibc-2.16, but I didn't see this problem with
glibc-mesboot or with the %bootstrap-glibc from architectures using
2.31.

Other workarounds I thought of were adding in a glibc-boot0 here to
replace libc for everybody or using an older version (the last one in
the 8 series), but this seemed like the least invasive option for now.

I've also added a comment so it'll be clearer what's happening there.

It turns out coreutils does allow for that.
