configure.ac: Append POSTLINK to LINK_SO for all platforms
The POSTLINK variable had been used only for darwin platforms, but
it's now used for WebAssembly/WASI as well. To make shared extension
libraries properly post-processed, we need to append POSTLINK to LINK_SO but it was done only for darwin platforms. This commit
generalizes the appending to all platforms.
