Normally, the makefile system will build all the software into a single
<tt>libname.o</tt> (pre-linked) object. This means the library is not
searchable and that the distinction between compilation units has been
- dissolved. Optionally, you can ask for a shared library (.so), archive library
- (.a) or to not have the default (relinked) library built. For example:</p>

Note that you normally do not need to specify the sources involved. The LLVM
Makefile system will infer the source files from the contents of the source
