[Buildroot] No core dump when killed with ABRT, SEGV, etc.

I get a proper core dump if a program actually causes a segfault, but
I can't figure out how to force a coredump by killing a running
On my desktop machines with glibc, this generates a core dump:
$ ulimit -c 9999999
$ <start program>
$ kill -ABRT <pid>
On my buildroot system, there's no core dump. The program is aborted
as expected, but it doesn't dump a core file. If the same program
tries to actually dereference a NULL pointer there is a core dump.
Why doesn't killing a process with SIGABRT or SIGSEGV cause a core
