[klibc] arm: use bx on thumb2 (v3)
Use klibc way to define a system dependent preprocessor
definition: disabled by default and enabled for newer arm.
Based on a patch by vorlon that got tested on his beagleboard,
should be functional equivalent. Tested on an arm Debian porter box
for the _KLIBC_ARM_USE_BX == 0 case.
