Fix embedding of modules on FreeBSD:

the constructor for the list of modules was run
after the constructors for the embedded modules
(which appended entries to the list).
As a result, the list appeared empty when it was
time to use it.

On linux the order of execution of constructor
was evidently different (it may depend on the
ordering of modules in the ELF file).

This is only a workaround - there may be other
situations where the execution of constructors
causes problems, so if we manage to find a more
general solution this workaround can go away.
