When working with Linux kernels, this version of the GNU C Library
requires Linux kernel version 2.6.0 or later.
All Linux kernel versions prior to 2.6.16 are known to have some bugs that
may cause some of the tests related to pthreads in "make check" to fail.
If you see such problems, please try the test suite on the most recent
Linux kernel version that you can use, before pursuing those bugs further.
