    Code move only; no functional change intended.
    
    Committer notes:
    
    Fix the build on Ubuntu 16.04 x86-64 cross-compiling to S/390, with this
    set of auto-detected features:
    
      ...                         dwarf: [ on  ]
      ...            dwarf_getlocations: [ on  ]
      ...                         glibc: [ on  ]
      ...                          gtk2: [ OFF ]
      ...                      libaudit: [ OFF ]
      ...                        libbfd: [ OFF ]
      ...                        libelf: [ on  ]
      ...                       libnuma: [ OFF ]
      ...        numa_num_possible_cpus: [ OFF ]
      ...                       libperl: [ OFF ]
      ...                     libpython: [ OFF ]
      ...                      libslang: [ OFF ]
      ...                     libcrypto: [ OFF ]
      ...                     libunwind: [ OFF ]
      ...            libdw-dwarf-unwind: [ on  ]
      ...                          zlib: [ on  ]
      ...                          lzma: [ OFF ]
      ...                     get_cpuid: [ OFF ]
      ...                           bpf: [ on  ]

      util/time-utils.c:93:2: note: include '<stdlib.h>' or provide a declaration of 'free'
    
    Do as suggested and add a '#include <stdlib.h>' to get the free() and strtoul()
    declarations and fix the build.
