[PATCH v4 bpf-next 09/15] samples/bpf: use own flags but not HOSTCFLAGS

From: Ivan Khoronzhuk
Date: Wed Oct 09 2019 - 16:41:57 EST

While compiling natively, the host's cflags and ldflags are equal to
ones used from HOSTCFLAGS and HOSTLDFLAGS. 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

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.
