Profile test fails on FreeBSD after 46571

[ararslan]

Noticed while getting FreeBSD CI set up on buildkite. On current master (12d329b, v1.10.0-DEV.635) with FreeBSD 12.2, one of the Profile test sets fails:

$ ./julia -e 'Base.runtests("Profile"; ncores=6)'
Running parallel tests with:
  nworkers() = 1
  nthreads() = 1
  Sys.CPU_THREADS = 6
  Sys.total_memory() = 23.959 GiB
  Sys.free_memory() = 16.695 GiB

I bisected the failure to #46571, and it happens to be the test set that's modified in that PR that's failing.
