+
+Fixes mips/musl build, since sgidefs.h is not present on all C libraries
+but on linux asm/sgidefs.h is there and contains same definitions, using
+that makes it portable.

+Subject: [PATCH] abseil: ppc fixes
+
+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)
+

+Subject: [PATCH] Don't match -Wnon-virtual-dtor in the "flags are needed to
+ suppress warnings in headers". It should fall through to the "don't impose
+ our warnings on others" case. Do this by matching on "-Wno-*" instead of
+ "-Wno*".
