Subject: [PATCH] Use configured `LD` for linking enc and ext libraries

"AR" was well propagated to the enc.mk and mkmf, but "LD" was not. This
caused the dynamic libraries to be linked with a linker found in the PATH,
which could be different from the one used in the Ruby build process.
This is especially important for cross-compilation, where the host
linker may not be compatible with the target system. (e.g. WebAssembly)
