-#  from being built for the library. This .o files may then be linked to by a

-#  (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.
