File _service:tar_scm:0007-add-lowlevellock_2_17_c.patch of Package glibc

Subject: [PATCH 7/9] build extra lipthreadcond so

since 78fe624d44b8f6489b2d0de9bfdc09290a719a7, lowlevellock.c depends futex-internal.h which uses the private symbol __GI___libc_fatal of glibc.
We can't reference it in libpthread-2.17.so. Therefore, recompile in libphtread-2.17.so
