As Will noticed, the header this check is currently done in
is asm-only, and is not meant to be included from C code.
This breaks compilation when compiled for a Thumb2-aware CPU.
Move the BX check to its own header, and revert 7a246fd.

The attached patch adds support for compiling arm uClibc as pure Thumb code.
This is needed because some recent ARM codes do not implement traditional ARM
mode. Specifically:
* Cortex-M1 - An extremely minimal FPGA based core that only implements
Thumb-1 (aka ARMv6-M).
* Cortex-M3 - A Thumb-2 only ARMv7-M core.
Most of uClibc already builds in Thumb mode, all that is left are a handful of
assembly bits.
Tested on arm-uclinuxeabi.

add support for using BX instruction for THUMB aware architectures
|
|
missing headers, other jump relocs removed
|
|
where the non-hidden version was used.

do seem to make noticable speed improvement...
