Subject: ppc: use std::mutex for host spinlocks
X-Git-Url: https://git.unchartedbackwaters.co.uk/w/?a=commitdiff_plain;h=761006e18843fc8e3c6785850f18bfc1b934bb64;p=francis%2Fwinuae.git

ppc: use std::mutex for host spinlocks

Use the C++ standard mutex implementation for the non-Windows PPC
spinlock wrapper instead of depending on GLib mutex types.

This keeps the shared PPC coordinator free of an extra host runtime
dependency when it is built outside Windows.
