xtensa: move byte-order macros out of arch.h These are macros that are expected to be defined at all times by the compiler. We need them at the very beginning of kernel.h for the k_thread definition, before it's possible to include arch.h. Make a special toolchain header for XCC compiler and place these defines in there. Otherwise inherit all the other GCC defines. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

xcc: fix __in_section_unique() and __COUNTER__ XCC assembler freaks out if a section name has __FILE__ in it, forward slashes and quotation marks confuse it and result in build errors. This is not a perfect fix, its possible for two sections to collide, but at worst this will result is some unnecessary space in noinit, fooling gc-sections. XCC also doesn't support __COUNTER__, use __LINE__ as a substitute. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
