+An all-in-one patch that fixes several issues:
+
+1) UnscaledCycleClock not fully implemented for ppc*-musl (disabled on musl)
+2) powerpc stacktrace implementation only works on glibc (disabled on musl)
+3) powerpc stacktrace implementation has ppc64 assumptions (fixed)
+4) examine_stack.cpp makes glibc assumptions on powerpc (fixed)
+
+Sourced from void linux
