    [gdb/testsuite] Remove duplicate of supports_gnuc
    
    In commit 9d9dd861e98 ("[gdb/testsuite] Fix regression in
    step-indirect-call-thunk.exp with gcc 7") I accidentally committed a duplicate
    of supports_gnuc, which caused:
    ...
    DUPLICATE: gdb.base/gdb-caching-proc.exp: supports_gnuc: consistency
    ...
    
    Fix this by removing the duplicate.
    
    Tested on x86_64-linux.
