> Any ideas why?

Yes. Your Jamfile has:

obj cfg : cfg.c ;

and absolutely nothing says that "cfg" depends on /lib-crc//crc,
so usage requirements of that target are not applied to 'cfg'. Did you try
adding /lib-crc//crc to the list of sources.

On a related note, why do you define a separate target for compiling 'cfg'?

And yet another note: if possible, please already provide complete testcase
which reproduces a problem, packed as zip, tar.bz2 or tar.gz archive.
Otherwise, I have to manually place the files in proper places, add missing
files, and so on, and it takes time.
