Comment # 11 on bug 1133294 from Martin Li������ka

Now it fails due to:

[   97s]
/usr/lib64/gcc/x86_64-suse-linux/10/../../../../x86_64-suse-linux/bin/ld:
/tmp/tests.EgwlFS.ltrans1.ltrans.o: in function `__wrap_GrabButton':

/home/abuild/rpmbuild/BUILD/xserver-1.20.10/test/xi2/protocol-xipassivegrabdevice.c:72:
undefined reference to `GrabButton'
[   97s] collect2: error: ld returned 1 exit status
[   97s] make[3]: *** [Makefile:1055: tests] Error 1

which is a -Wl,-wrap,GrabButton used in tests. -Wl,-wrap is not supported by
LTO.
A possible fix would be disabling of LTO in tests.
