+
+From chimera patch:
+"Clang has -nostdlib++, which can be used more effectively than disabling
+all and then hardcoding linking against libgcc (which we do not have)"
+
+Obsoletes graphite2-1.3.14-fix-nodefaultlibs.patch whose description was:
+```
+See https://github.com/silnrsi/graphite/pull/44.
+
+Drop -nodefaultlibs:
+- graphite is written in C++ which makes avoiding libstdc++ (or libc++) a dubious
+  goal;
+- this ends up breaking e.g. x86/musl because we need to inject -lssp_nonshared,
+  but it wouldn't be surprising if it broke other exotic targets too.
