+; Solaris kernel modules use non-standard ELF constructions to express inter-
+; module dependencies, namely a DT_NEEDED tag inside a relocatable ELF file.
+; The Solaris linker can generate these automatically; since yasm can't
+; produce an ELF file which quite fits Solaris's requirements we create one
+; manually using flat binary output format.  In order to save unnecessary
+; repetition, this file defines macros for the repetitive bits which can be
+; reused by the actual dependency objects.  Certainly not the nicest way to
+; get the effect we want, but probably a reasonable compromise between
+; cleanness and required effort.
