Autoreconf is not necessary anymore.
WavPack "autodetects" CPU type to enable ASM code. However, the assembly code
for ARM is written for ARMv7 only and building WavPack for an ARM-non-v7
architecture will fail. We explicitly enable ASM for the supported
architectures x86, x64 and ARMv7 and disable it for all others.
