-frepo is handled by the collect2 program, which then calls either the
GNU or the "native" linker.

No, the collect program handles the constructor problems on other systems.
See the g++ FAQ for a discussion (http://www.cygnus.com/misc/g++FAQ_toc.html).
It may not be able to deal with global constructors in shared libraries,
though.

g++ never worked with only a native ld on non-ELF systems.  Something
has to resolve the constructors.

If, for a particular platform other than ELF, there is a way to make
shared libraries work with the native linker, and someone wants to
contribute it, fine, but it shouldn't be a priority when the workaround
"use the GNU linker" exists.
