    gdb, btrace: Fix rn-dl-bind.exp for new icx remark.
    
    When running the test with the latest Intel compiler:
    
    Running gdb/gdb/testsuite/gdb.btrace/rn-dl-bind.exp ...
    gdb compile failed, icpx: warning: treating 'c' input as 'c++' when
    in C++ mode, this behavior is deprecated [-Wdeprecated]
    
    The test doesn't seem to test something specifically for C++,
    so I removed the C++ compilation option. Alternatively we could rename
    rn-dl-bind.exp.c to rn-dl-bind.exp.cc.
