+    gcc/musl: rework SSP-support
+    
+    Make musl provide libssp_nonshared.a and make GCC link it unconditionally
+    if musl is used. This should be a no-op if SSP is disabled and seems to be
+    the only reliable way of dealing with SSP over all packages due to the mess
+    that is linkerflags handling in packages.
