New bootstrap failure on sparc-solaris2.7, fails to define "sparc"

Neil,

I'm getting a new bootstrap failure on sparc-sun-solaris2.7 within the
last day or so., probably related to recent changes you made.  It dies
in stage1 building any libgcc target file.  E.g.

The problem appears to be that neither "sparc" nor "__sparc" gets
defined.  (If I add -Dsparc or -D__sparc to the above invocation, the
compilation succeeds.)

Would you please take a look?
