    testsuite: Fix pr119160.c for non-glibc targets [PR119862]
    
    Testcase pr119160.c fails with symbol referencing errors for
    `__cyg_profile_func_enter` and `__cyg_profile_func_exit` on non-glibc
    systems.
    
    This patch adds empty definitions for `__cyg_profile_func_enter`
    and `__cyg_profile_func_exit` in order to prevent those errors.

            * gcc.dg/pr119160.c: Added empty definitions for
            `__cyg_profile_func_enter` and `__cyg_profile_func_exit`
            functions.
