+/* If the entry point was not specified as an address, then add the
+   symbol as undefined.  This will cause ld to extract an archive
+   element defining the entry if ld is linking against such an archive.
+
+   We don't do this when generating shared libraries unless given -e
+   on the command line, because most shared libs are not designed to
+   be run as an executable.  However, some are, eg. glibc ld.so and
+   may rely on the default linker script supplying ENTRY.  So we can't
+   remove the ENTRY from the script, but would rather not insert
+   undefined _start syms.  */
