  20           If you say 'y' here, functions and constants required by the
  21           ARM EABI will be built into the library.  You should say 'y'
  22           if your compiler uses the ARM EABI, in which case you will also
  23           need a kernel supporting the EABI system call interface.
  24
  25           If you say 'n' here, then the library will be built for the
  26           old Linux ABI.

  33           Say 'y' here to force building uClibc in thumb mode.
  34           Say 'n' to use your compiler's default mode.

  39           Say 'y' to use BX to return from functions on your thumb-aware
  40           processor. Say 'y' if you need to use interworking. Say 'n' if not.
  41           It is safe to say 'y' even if you're not doing interworking.

  48           Say 'y' to use LDREX/STREX ASM ops.
