           Summary: Can't compile libiberty for bfin-elf target.
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: mon...@monami-software.com
              Host: i386-apple-darwin10.5.0
            Target: bfin-elf
             Build: i386-apple-darwin10.5.0


configuration was failed with this message.
configure:5724: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

This issue is not similar to #46553.

It is required -mcpu option by bfin-elf-gcc. But there is no case in
configuration phase.
So  the link test is failed with this message: "xgcc: error: no processor type
specified for linking"
