If there are dlopen()ed .so modules linked with "ld -Bshareable" rather than
"cc -shared", it makes sense.  ("cc -shared" still passes -lc to ld.)

For shared objects, "cc -shared" works on NetBSD 1.4+ and all ELF versions
of NetBSD.  However, only "ld -Bshareable" works correctly on a.out, NetBSD
1.3.x and earlier.
