right. sparc/sol2-64.h was included too late. The following patch fixes
this. Other approaches to reordering the headers ran into various
issues since TARGET_DEFAULT is defined and redefined in several places.
The patch allowed a sparcv9-sun-solaris2.11 bootstrap to run well into
building the target libraries (failed configuring libgfortran since I'd
mis-merged the 32-bit and 64-bit gmp.h), a sparc-sun-solaris2.10
bootstrap is still running.
I'll probably fix the gmp.h issue, rebuild the sparcv9-sun-solaris2.11
configuration and commit unless I find problems or you disapprove of the
approach.

* config/sparc/sol2-64.h (TARGET_DEFAULT): Remove.
(TARGET_64BIT_DEFAULT): Define.
* config.gcc (sparc*-*-solaris2*): Move sparc/sol2-64.h to front
of tm_file.
* config/sparc/sol2.h [TARGET_64BIT_DEFAULT] (TARGET_DEFAULT): Define.
