Some buggy NPTL threading implementations include the guard area within the stack size allocations. In this case we need to allocate an extra page to account for the guard area since we only have two pages of usable stack on Linux. Added an autoconf test that detects such implementations by running a test program designed to segfault if the bug is present. Set a flag NPTL_GUARD_WITHIN_STACK that is tested to decide if extra stack space must be allocated for the guard area. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
