Normal architectures:

 - Big endian: avr32, frv, m68k, openrisc, parisc, s390, sparc

 - Little endian: alpha, blackfin, cris, hexagon, ia64, metag, mn10300,
                  score, unicore32, x86

 - Choose in config time: arc, arm, arm64, c6x, m32r, mips, powerpc, sh

Special architectures:

 - Deside by compiler: microblaze, tile, xtensa.

 - Deside by building host: um

 - Next, need improve Kbuild to probe endian to deside whether need mark
   __BUILDING_TIME_BIG_ENDIAN__ before real config.

Another improvements:

 - score: use '\t' instead of ' '.

 - s390: sort the select value in alpha order.
