When you type it, just add the relative path to the tools subdirectory of a wine build compiled for your host system.
If you're on a 64-bit system, all you need to do to build a 64-bit wine is pass The problem is that by itself, that build will only run applications compiled for 64-bit Windows.
Once you have the source code, it's time to grab all of the necessary build tools and libraries.
If you have a unix with package management, probably the quickest way to find most of the software you need is to use whatever "build dependency" command your package manager offers.
You might have heard of knows what steps it can skip if you change the source code and recompile.
So if you don't want to recompile all of wine from scratch after every patch, don't disturb the object files.
