+# When libraries are built, they are allowed to optionally define the

+# from being built for the library. This .o files may then be linked to by a
+# tool if the tool does not need (or want) the semantics a .a file provides
+# (linking in only object files that are "needed"). If a library is never to
+# be used in this way, it is better to define DONT_BUILD_RELINKED, and define
+# BUILD_ARCHIVE instead.
+#
+# Some libraries must be built as .a files (libscalar for example) because if
+# it's built as a .o file, then all of the constituent .o files in it will be
+# linked into tools (for example gccas) even if they only use one of the parts
+# of it. For this reason, sometimes it's useful to use libraries as .a files.
