	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.

	Put the call_via_rx code into each executable - call_via_ip cannot possibly work if called through the PLT! ldso requires this code too as it is not linked with the crt stuff and thumb ldso does make calls via a register. The patch puts the code into crti.S so that it is linked into every normally built application (if thumb or interworking is selected). This is only 30 extra bytes and it works - the previous code did not because nothing both implemented and exported the APIs (they were in libgcc, but not in the version script). crti.S and crtn.S is also brought up to date with GCC 3.4.4 - this is essential for thumb support because the .init and .fini sections must use arm or thumb code to match the compilation of the libraries. Note that code which pushes stuff into .init or .fini must be compiled with or without -mthumb to match the uclibc compilation - and gcc itself (which does do this) must therefore be compiled to match.
