[Boost-build] Target paths idea

I had just got a totally crazy idea -- we have some algorithms
to compute target paths, and --abbreviate-paths options, and it
not quite good yet.

How about just using MD5 or SHA-1 of build properties to form
target path? Might sound scary, but after working with git for
a bit, I find that using SHA-1 to identify things is not so
bad, as copy-paste works. To make things easier, we might
put a file in each build directory that lists all the properties
of the files in that directory.

Comments?
