Patches for FreeBSD

on FreeBSD, gnu make is called gmake, so we can't call "make" directly, also, freebsd's statvfs works fine, no need for a statvfs64.

I have two other local patches :

Install the sync-exclude.lst in another name so that we don't overwrite it by mistake:

FreeBSD doesn't need -ldl but does need -linotify:
