+ 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.
