[RFC PATCH kernel] gcc-goto.sh: Allow to pass with CONFIG_DEBUG_INFO_SPLIT=y
With just CONFIG_DEBUG_INFO=y, the makefile adds "-g" to KBUILD_CFLAGS/KBUILD_AFLAGS and the test passes. However, if CONFIG_DEBUG_INFO_SPLIT is also enabled, the makefile adds "-gsplit-dwarf" instead which makes the test fail with $?==1 because of objcopy trying to split the debug info: objcopy: Warning: '/dev/null' is not an ordinary file This changes the output to $(mktemp) which fixes the problem. I am pretty sure there better ways, this is just to demonstrate the bug. gcc 5.4.1, ppc64le (does not really matter).
