Immediately after the IRA merge, sparc-sun-solaris2.11 bootstrap is broken:
stage2 libgcc fails to configure:
checking for suffix of object files... configure: error: in
`/vol/gccsrc/obj/reghunt/89389/sparc-sun-solaris2.11/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

Running cc1 directly gives the same error. Running cc1 under gdb directly gets
me a segfault instead of SIGBUS:
