    testsuite, Objective-C: Fix duplicate libobjc cases.
    
    Two of the encode testcases include '-lobjc' as their dg-options.
    Since the library is already appended as part of the generic testsuite
    handling,  this means that two instances appear on the link line leading
    to spurious warnings from Darwin's new linker.
    
    gcc/testsuite/ChangeLog:
    
            * obj-c++.dg/encode-10.mm: Remove unneeded '-lobjc' option addition.
            * obj-c++.dg/encode-9.mm: Likewise.
