ZFS_AC_CONFIG_USER_ZLIB
Additional build system update for libefi library. This include updating all the Makefile.am to have the correct include paths and libraries. In addition, the zlib m4 macro was updated to more correctly integrate with the Makefiles. And I added two new macros libblkid and libuuid which will be needed by subsequent commits for blkid and uuid support respectively. The blkid support is optional, the uuid support is mandatory for libefi.

ZFS_AC_CONFIG_USER_LIBUUID
ZFS_AC_CONFIG_USER_LIBBLKID
Add configure check for -Wframe-larger-than=<size> It turns out the gcc option -Wframe-larger-than=<size> which I recently added to the build system is not supported in older versions of gcc. Since this is just a flag to ensure I keep stack usage under control I've added a configure check to detect if gcc supports it. If it's available we use it in the proper places, if it's not we don't.

ZFS_AC_CONFIG_USER_FRAME_LARGER_THAN
Autoconf check for buggy stack guard region 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>
