nmap fix/diff

[Okan Demirmen <okan_(_at_)_demirmen_(_dot_)_com>]

nmap in -current and previous versions of the port had some problems
on 64bit archs, namely realloc() and datalink errors. I finally had
a chance to track that down. So far this diff on -current has been
tested on i386 and sparc64, however it needs more testing, and
certainly comments if anyone has any. The code is a mess, so this
is merely a hack, but I might take the idea upstream and fix the
configure scripts and whatnot, when I have the time.

Also, I don't mind taking maintainer on this (included in diff).

Thanks,
Okan
