    ld: Skip bootstrap tests for -fprofile-generate=
    
    Make plug_opt available to all linker tests.  Skip bootstrap tests when
    linker is compiled with -fprofile-generate=.
    
            * testsuite/ld-plugin/lto.exp (plug_opt): Moved to ...
            * testsuite/config/default.exp (plug_opt): Here.  New.
            * testsuite/ld-bootstrap/bootstrap.exp: Skip when linker is
            compiled with -fprofile-generate=.
