Yes, they do work on a.out.

The only difference between a.out and ELF is that missing dependencies on
a.out (where someone forgets to link a library with its dependency) are not
noticed until runtime, whereas GNU ld notices the undefined symbols at link

However, in order to make sure that programs properly link in all needed
system libraries (even for NOPIC platforms, where shared objects do not
exist), we avoid using dependencies on libraries in /usr/lib.  This forces
programs to link in all necessary libraries from /usr/lib, so even
statically-linked NOPIC platforms will still be able to compile and link
such programs.
