error: implicit declaration of function... during installation or building

[dofuuz]

Python-SoXR now supports x86 and ARM processors. (ppc64le is also supported but it's not being intensively tested.)

In other platforms, an error like below can occur during pip installation or building.

error: command '/usr/bin/gcc' failed with exit code 1

In this case, see BUILDING.md and build Python-SoXR using system libsoxr.

TODO: Automatically build Python-SoXR using system libsoxr if needed.

• [ ] Guide dynamic link build if static build fails
• [x] Expose soxr_version() as __libsoxr_version__.

Fixed with v0.5.0a1
