From 612eb45a2e7a0b35cc3790870e6d0cc42eb50c74 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>

Subject: [PATCH] sdksyms.sh: Make sdksyms.sh work with gcc5.

gcc5's cpp inserts patterns like this:

extern
      __attribute__((visibility("default")))
                int WaitForSomething(int *
    );

This patch make sdksyms.sh work with this. Note my awk skills are weak, so
there likely is a better way to deal with this.
