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 -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.

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
