Support building on FreeBSD

[GoogleCodeExporter]

Google Gears user "freedom <koansin.tan>" was able to build on FreeBSD 
after applying the changes below.

Sure, actually, it's quite trivial.
The steps I used to build it:

1). build Gecko SDK from MOZILLA_1_8_BRANCH
2). install GNU Make and GNU m4
3). add configurations for FreeBSD to tools/config.mk, change tools
rules.mk to use gmake and gm4)
4). comment out #include <malloc.h>
5). cast argument passing to wcslen() to (wchar_t*)
6). gmake

It is already been nearly a year since my last comment. Any idea on when this 
might
be scheduled?
