Subject: [PATCH] allow libucw to depend on other libraries

I need it when CONFIG_PCRE is enabled.  After the internal copy of a
reliable regexp library has been deleted from Sherlock source codes, I
cannot compile Sherlock on Darwin with the default libraries.  Therefore I
have installed pcre, but it isn't automatically linked to everything yet.
