config/Makefile:187: No libelf found, disables 'probe' tool, please install elfutils-libelf-devel/libelf-dev
config/Makefile:251: No libunwind found, disabling post unwind support. Please install libunwind-dev[el] >= 0.99
config/Makefile:279: slang not found, disables TUI support. Please install slang-devel or libslang-dev
config/Makefile:292: GTK2 not found, disables GTK2 support. Please install gtk2-devel or libgtk2.0-dev
config/Makefile:346: The path '/usr/bin/python-config' is not executable.
config/Makefile:350: No python-config tool was found
config/Makefile:350: Python support will not be built
config/Makefile:444: No numa.h found, disables 'perf bench numa mem' benchmark, please install numa-libs-devel or libnuma-dev

My bad, its still there, sorry for the noise 8-)

I'm testing removing devel packages, one by one, removing gtk2-devel provides
the biggest reduction in build time, no surprises :)
