Ok, I've just tried your changed version and get:

With nptl:
GCONV_PATH=/builds/glibc/hammer+nptl/iconvdata LC_ALL=C   /builds/glibc/hammer+nptl/elf/ld-linux-x86-64.so.2 --library-path /builds/glibc/hammer+nptl:/builds/glibc/hammer+nptl/math:/builds/glibc/hammer+nptl/elf:/builds/glibc/hammer+nptl/dlfcn:/builds/glibc/hammer+nptl/nss:/builds/glibc/hammer+nptl/nis:/builds/glibc/hammer+nptl/rt:/builds/glibc/hammer+nptl/resolv:/builds/glibc/hammer+nptl/crypt:/builds/glibc/hammer+nptl/nptl /builds/glibc/hammer+nptl/rt/tst-timer4  > /builds/glibc/hammer+nptl/rt/tst-timer4.out

clock_gettime returned timespec = { 1082217097, 179058000 }
clock_getres returned timespec = { 0, 999848 }


And with linuxthreads:
