now that image format is not changed when scaling the performance
impact with this change is almost none, in most cases you will
(should) not notice a difference. if you care about performance
you most likely build with -mtune=native anyway so that the
compiler can better optimize things for the hardware.

now that the assembler language is enabled in the build system the macro
turned out to be a bit bogus and it has to handle sources control too
because some CPU specifiec sources were, previously, added unconditionally
to targets leading to build failures (especially with assembly).
CPU tests now declare variables that are cached and can be changed by the
user to avoid touching parent scope from the test macros (previously
functions for that reason).
