Its behavior is the same as *ld-flags*, and cannot help for the same
reasons. I really need that -Wl,--whole-archive before all the .a's
and --no-whole-archive after, and/or -force_load flag before each of
them on Darwin (or lld).

Whoa, so even the 2005 code of asdf-ecl was outdated. Well, thanks for that,
it will be fixed in 3.2.1 if not 3.2.0.

In other news, with a patch to ASDF in !66 and my latest cffi fork,
by linking all individual objects rather than .a files, I managed to
statically compile
an executable with C extension (hello/chello from the bazelisp example):
