sbc: better compatibility with ARM thumb/thumb2
ARM assembly optimizations fail to compile in thumb mode, but are fine
for thumb2. Update ifdefs in the code to make use of ARM assembly only
when it is safe and also make sure that no optimizations are missed
when compiling for thumb2.
The problem was reported by Paul Menzel:
https://tango.0pointer.de/pipermail/pulseaudio-discuss/2011-February/009022.html
This patch is tested with OpenEmbedded using `minimal-uclibc` for `MACHINE = "at91sam9260ek"`.
Note that changes to ipc.h from 8f3ef04b had to be manually reapplied.
