Clang on Windows doesn't use pthread for now, while MinGW does. Removing
`-pthread` option with MS linker fixes the following warning:
clang: warning: argument unused during compilation: '-pthread'
[-Wunused-command-line-argument]
Option `--no-as-needed` is meaningless for PE output. Disabling it on
Windows fixes the following warning:
LINK : warning LNK4044: unrecognized option '/-no-as-needed'; ignored
Fixes: 98edcbb5a ("eal/windows: introduce Windows support")
