When cross compiling it should have own, used for target arch. While verification, for arm, arm64 and x86_64 the following flags were used always: -Wall -O2 -fomit-frame-pointer -Wmissing-prototypes -Wstrict-prototypes So, add them as they were verified and used before adding Makefile.target and lets omit "-fomit-frame-pointer" as were proposed while review, as no sense in such optimization for samples.
