The webrtc-audio-processing configure script assumes that if the host_cpu part of the tuple is "arm", then ARM instructions are available. This is obviously incorrect for ARM Cortex-M platforms, which only support the Thumb-2 instruction set. In order to address this, we add a patch, 0001-configure.ac-fix-architecture-detection.patch, which changes how webrtc-audio-processing detects the architecture: instead of relying on the host_cpu part of the tuple, it relies on the built-in definitions of the compiler. Not only it fixes the Cortex-M detection, but it also enables ARMv7 optimizations on ARMv7-A: until now they were only enabled when the host_cpu part of the tuple was armv7, which is never the case in Buildroot. However, once this issue is fixed for Cortex-M, the build nonetheless fails later due to the usage of NPTL-only functions. So we change the thread dependency to a NPTL dependency.
