Use auditwheel so apt install {pkg} isn't necessary

[dhermes]

For example with NumPy:

.../bin/auditwheel repair \
  --plat linux_x86_64 \
  numpy-1.15.0-pp360-pypy3_60-linux_x86_64.whl \
  -w .../wheelhouse/

results in a wheel with

$ tree numpy/.libs/

This also rewrites the dependencies in the binaries, e.g.

$ readelf -d numpy/core/multiarray.pypy-41.so | grep -i library
 0x0000000000000001 (NEEDED)             Shared library: [libcblas-69d2105f.so.3.10.3]

It also makes sure that dependencies are copied recursively. For example, libatlas isn't directly depended on by any of the .so extension modules but it is required transitively:

$ readelf -d numpy/.libs/libcblas-69d2105f.so.3.10.3 | grep -i library
 0x0000000000000001 (NEEDED)             Shared library: [libatlas-88623f80.so.3.10.3]

 0x000000000000000e (SONAME)             Library soname: [libcblas-69d2105f.so.3.10.3]
