    cobol: Avoid conflict with timespec_t in system headers [PR119217]
    
    util.cc doesn't compile on Solaris:
    
    /vol/gcc/src/hg/master/local/gcc/cobol/util.cc:2135:7: error: using 
typedef-name ‘timespec_t’ after ‘class’
     2135 | class timespec_t {
          |       ^~~~~~~~~~
    
    This happens because <time.h> declares timespec_t itself.  In fact,
    POSIX.1 reserves every *_t identifier, so this is benign.
    
    To avoid the problem, this patch renames the cobol timespec_t to
    cbl_timespec.
    
    Bootstrapped without regressions on amd64-pc-solaris2.11,
    sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu.
