Hi, Isak!
According to manifest documentation [1] you can specify crate type (dynamic or
static lib or rlib) using crate_type option:
[[lib]]
…
crate_type = ["dylib", "staticlib"]
The above configuration should build you both .a and .so files.
[1]: http://crates.io/manifest.html, search for "crate_type" w/o quotes
