You have something like $(ARCH)$(ARCH) somewhere in your Makefile.
ARCH=o-optimize and the expansion is doing this.

As a historical tidbit ARCH used to have more options than optimize
like o-debug and o-profile but those have long been removed. We always
build with full debug info and as high of optimization is felt to be correct
and safe for a particular BSP.
