# commit 0666a64a1f481bf43f92195b445d905b4dc37c2a
# Author: Alexey Dobriyan <adobriyan@gmail.com>
# Date:   Mon Aug 2 23:43:15 2021 +0300
# 
#     isystem: delete global -isystem compile option
#     
#     Further isolate kernel from userspace, prevent accidental inclusion of
#     undesireable headers, mainly float.h and stdatomic.h.
#     
#     nds32 keeps -isystem globally due to intrinsics used in entrenched header.
#     
#     -isystem is selectively reenabled for some files, again, for intrinsics.
#
