Another way to fix this is the following patch:
--- a/include/target.mk
+++ b/include/target.mk
@@ -177,8 +177,8 @@ ifeq ($(DUMP),1)
CPU_CFLAGS_octeonplus = -march=octeon+ -mabi=64
endif
ifeq ($(ARCH),i386)
- CPU_TYPE ?= pentium
- CPU_CFLAGS_pentium = -march=pentium-mmx
+ CPU_TYPE ?= pentium2
+ CPU_CFLAGS_pentium2 = -march=pentium-mmx
CPU_CFLAGS_pentium4 = -march=pentium4
endif
ifneq ($(findstring arm,$(ARCH)),)
The problem with that one is that I have no hardware to test it on. In
theory it should work as mtune is identical.
