Currently GNU 'ls' dynamically links a whole bunch of libraries, libraries like 
libpcre and liblzma.  Can we figure out some way to remove the runtime 
dependencies on these libraries?  It's better if a core utility like 'ls' avoids 
libthis and libthat unless the libraries are vital to its function, which these 
shouldn't be.

I installed the attached patches to get rid of one unnecessary library, libacl, 
on GNU/Linux.  Can we do better and get rid of more dependencies?  Perhaps using 
techniques similar to what was used to get rid of libacl?
