From the ld.gold source:
const char* name = parameters->options().soname();
if (name == NULL)
name = parameters->options().output_file_name();
That means by default it uses `-o {output}` as the verdef aux name,
which is random every time due to Go's build system. By passing in
`--soname={somethingexplicit}` we can instead have a deterministic
verdef.
This commit makes wireguard-android reproducible.
