Subject: xen/x86: Add -Wnested-externs to CFLAGS
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~10269

xen/x86: Add -Wnested-externs to CFLAGS

This will catch any new extern declarations that happen actually
inside function bodies.  Unfortunately there's no equivalent
warning for extern declarations at rootl level in .c files.
