By the way, I'm strongly opposed to this: it should be, at best, in the
profiles.
For instance, as long as bug #192403 isn't fixed, as-needed will cause
*a lot* of build failures on fbsd since gcc specs are broken and wont
append the -lc for shared libraries and -lpthread when -pthread is
used if I remember correctly.
