(not for landing) option to use devel/libexecinfo

(In reply to Yuri Victorovich from comment #9)
-fno-omit-frame-pointer is default on FreeBSD for GCC and Clang regardless =
of
-O<N> level. Fortunately, base system doesn't pass -fomit-frame-pointer by
default and ports encourage either to remove or hide the flag behind
OPTIMIZED_CFLAGS option.

  $ gcc6 -Q --help=3Doptimizers -O3 | fgrep frame-pointer
    -fomit-frame-pointer                  [disabled]
