build: fake PEP440 versions

If the current version is not exactly a tag, use a local version
specifier to fix it up. PEP 440 uses the "+" separator and only allows
alphanumeric and dot, so use dot for further separations.

Old devel build: 5.7+155-a163cc36d06b
New devel build: 5.7+hg155.a163cc36d06b

# By default Rust will not export dynamic symbols from built executables.
# Python symbols need to be exported from executables in order for that
# executable to load Python extension modules, which are shared libraries.
# Otherwise, the extension module / shared library is unable to resolve
# Python symbols. This file contains target-specific configuration
# overrides to export dynamic symbols from executables.
#
# Ideally we would achieve this functionality via the build.rs build
# script. But custom compiler flags via build scripts apparently only
# support limited options.
