This helps when using a cross-compiler for building intel-speed-select, currently, its hardcoded to pick libnl3 headers from build host which may not be same as build target when cross compiling. cc -print-sysroot will print nothing if compiler is configured without a sysroot and result in same string as it is now. Fixes errors with gcc configured with host include poisoning e.g. cc1: error: include location "/usr/include/libnl3" is unsafe for cross-compilation [-Werror=poison-system-directories] Signed-off-by: Khem Raj <raj.khem@gmail.com> [ srinivas: Changelog edits for checkpatch warning ] Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
