Comment:
In GHC we don't currently support the kind of ABI versioning you get in C
libraries where you can have a `.so` that supports multiple ABI versions.
Instead we encode the version directly in the filename of the `.so`, as in
`libHSbase-ghc6.12.3.so`. Even this is quite suspect as there is no
guarantee that a given `libHSbase-ghc6.12.3.so` has the same ABI as
another `libHSbase-ghc6.12.3.so`. The problem is that GHC is not capable
of producing a library that has a consistent, predictable, ABI. I'd like
to fix this someday, but it's not a simple task.
For linker scripts see #2615.
