As of GCC 4.6, specific kernel 2.6.32 header files do not compile cleanly without warnings. One specific example of this is the arch/x86/include/asm/percpu.h file. Thus, a few of the configure tests were getting hung up on this and the '-Wno-unsued-but-set-variables' compile option had to be introduced. Signed-off-by: Prakash Surya <surya1@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #459
