Sorry, forget the suggestion, it doesn't work since it leads to CFLAG
-march="" and the same problem occurs.
For my case this works:
--- sys/boot/efi/Makefile.inc.orig      2014-09-23 16:22:46.000000000 +0200
+++ sys/boot/efi/Makefile.inc   2014-09-23 16:46:30.000000000 +0200
@@ -2,6 +2,10 @@
 
 BINDIR?=       /boot
 
+.if ${CPUTYPE} == "core-avx2"
+CPUTYPE=       core-avx-i
+.endif
+
 .if ${MACHINE_CPUARCH} == "i386"
 CFLAGS+=        -march=i386
 .endif
