           Summary: [4.8 Regression] LTO bootstrap failed with
                    bootstrap-profiled
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: hjl.to...@gmail.com


On Linux/x86-64, revision 189467 failed to profiledbootstrap:

checking for suffix of object files... configure: error: in
`/export/gnu/import/git/gcc-test-profile/bld/x86_64-unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[5]: *** [configure-stagefeedback-target-libgcc] Error 1

when configured with

--prefix=/usr/local --enable-clocale=gnu --with-system-zlib --enable-sh
ared --with-demangler-in-ld --with-build-config=bootstrap-lto --with-fpmath=sse 

"--prefix=/usr/local" is the key to trigger this regression.
The stage 3 compiler is miscompiled.  Revision 189349 is OK.
