meson guarantees this is portable, so this also allows us to remove a
is_windows switch.
Hi Gabriel,
On Windows, there are at least three different compilation options:
* MinGW-w64 with posix threads
* MinGW-w64 with win32 threads (different download)
* Clang without threads support
The Windows EAL library doesn't use a threads package and instead uses
it's own wrappers around the native Windows system calls. Given that, I
believe the existing behaviour of not specifying the pthreads package
for a Windows build is correct and shouldn't be changed.
Regards,
Nick
