assembler issue - no such instruction

Hi all,

I am trying to compile ArcticFox on OpenBSD 6.5. On 6.4 I had no
issues,it compiled and worked!
I am using gcc 4.9 from ports and it dies with:

 2:16.64 host_pathsub.o
 2:16.85 /tmp//cctgHRHn.s: Assembler messages:
 2:16.85 /tmp//cctgHRHn.s:36: Error: no such instruction: `vmovaps

 2:16.87 In the directory
/home/multix/code/Arctic-Fox/obj-amd64-unknown-openbsd6.5/config
 2:16.87 The following command failed to execute properly:
 2:16.87 egcc -o host_pathsub.o -c -DXP_UNIX -MD -MP -MF
.deps/host_pathsub.o.pp -O2 -march=sandybridge -DUNICODE -D_UNICODE
-I/home/multix/code/Arctic-Fox/config -I. -I../dist/include
-I/home/multix/code/Arctic-Fox/obj-amd64-unknown-openbsd6.5/dist/include/nspr
/home/multix/code/Arctic-Fox/config/pathsub.c
 2:16.87 gmake[5]: ***
[/home/multix/code/Arctic-Fox/config/rules.mk:889: host_pathsub.o] Error 1

From looking on the internet, this seems an assembler problem

I tried to force AS to gas, but it did not change, maybe egcc is not
respecting it
