Those bootstraps have completed now.  The Solaris 11 and 32-bit Solaris
10 results look good, both libffi and libjava, but 64-bit Solaris 10
still FAILs:

FAIL: libffi.special/unwindtest.cc  -shared-libgcc -lstdc++ execution test
terminate called after throwing an instance of 'int'

Comparing sparcv9 fficonfig.h between S10 and S11, I see only one
difference:

--- fficonfig.h.s10     2015-01-28 00:45:48.714103199 +0100
+++ fficonfig.h.s11     2015-01-27 18:27:05.122136400 +0100

 /* Define if your assembler and linker support unaligned PC relative relocs.
    */
-/* #undef HAVE_AS_SPARC_UA_PCREL */
+#define HAVE_AS_SPARC_UA_PCREL 1

And checking the GCC 4.9 v9.S, I found that the attached change also
fixes those FAILures.  Tested for both 32 and 64-bit on S10 and S11.
