Subject: Paul Brook writes: 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.
