Because some of the symbols are not otherwise referenced, GCC would like
to remove them.

Commit e8d340de ("Remove a.out support from nlist()") introduced a copy
of the definition of nlist from a.out.h. However, as well as having
n_name inside n_un, on the various BSDs n_name could also be accessed
as a direct member of nlist, and this is made use of by FreeBSD's
usr.bin/netstat/main.c. Thus we should also add the same enclosing
anonymous union.

On IA64 this is only the case in the ELF binary, but it gets normalized
when loaded at run-time.

At least on IA64 and PowerPC 64-bit ELFv1, the functions are stored in
the .text sections but they are accessed through a function descriptor
stored in a data section, for example for PowerPC 64-bit ELFv1 that
section is called .opd.
We should take this into account when checking the n_type for the
functions we have requested information from nlist().
