It need not be that complicated. I forgot to configure using
--with-gnu-ld=no, but at the finally linking step, I just ran "gcc
-B/usr/ccs/bin/" instead of normal gcc. I see that gcc still runs
collect2, but the system ld is eventually run and temacs does produce
an xemacs that does start and run.
I think this should definitely be in the PROBLEMS file.

Yes (I don't have time to figure out _why_ GNU ld is failing).

** SunOS/Solaris
+*** Dumping error when using GNU binutils / GNU ld on a Sun.
+
+Errors similar to the following:
+
+ Dumping under the name xemacs unexec():
+ dldump(/space/rpluim/xemacs-obj/src/xemacs): ld.so.1: ./temacs:
+ fatal: /space/rpluim/xemacs-obj/src/xemacs: unknown dynamic entry:
+ 1879048176
+
+are caused by using GNU ld. There are several workarounds available:
+
+In XEmacs 21.2 or later, configure using the new portable dumper
+(--pdump).
+
+Alternatively, you can link using the Sun version of ld, which is
+normally held in /usr/ccs/bin. This can be done by adding
+-B/usr/ccs/bin to CFLAGS used to configure XEmacs, or by uninstalling
+GNU ld.
+
*** Link failure when using acc on a Sun.
To use acc, you need additional options just before the libraries, such as
