I manually generated all the missing support files and re-ran the testsuite.  
I'm now getting 7 failures out of 137 (log attached).

1. incremental_test:      suspect this is not really an error (failed v2.21 too)
2. ver_matching_test.sh:  __bss_start not local, rtld issue? real issue? (failed on v2.21 too)
3. exception_static_test: likely real problem.  gdb log attached
4. intpri2:               likely real problem.  gdb log attached
5. relro_test:            no relro support in rtld, ignore
6. relro_now_test:        no relro support in rtld, ignore
7. relro_strip_test:      no relro support in rtld, ignore

I'm most worried about tests 3 and 4.
The exception didn't get caught back in exception_test_1.cc.  System compiler is gcc 4.4.7 
(2011-10-25 snapshot) using dl_iterate_phdr for exception handling.
Test 4 may have failed due to the changed ctors setting in option.h ??

Any comment/guidance about the testsuite results is appreciated.
It looks like gold is fairly healthy on DragonFly after altering option.h though.
