Profiled-bootstrapped/regtested on x86_64-suse-linux (mainline), on 
sparc64-sun-solaris2.9 (4.0 branch) and sparc64-sun-solaris2.8 (4.0 branch),
installed on both branches.

Mainline profiled-bootstrap is broken on SPARC/Solaris because of a segfault 
in output_line_info triggered by -freorder-blocks-and-partition.

Thanks for the (quick) review.
