We don't use lgcc_s but missing lgcc_s or another library cause test to fail. So use -nostdlib. We need to use -Werror to avoid warning-generated case to be accepted. Clang uses -nopie rather than -no-pie. Check both and use whichever one works. Additionally android clang passes -pie to the linker even though it doesn't define __PIE__. So if compilation without no-pie logic fails add -nopie/-no-pie even if __PIE__ is not defined.
This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable.

Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
