   5     gcc/musl: rework SSP-support
   6
   7     Make musl provide libssp_nonshared.a and make GCC link it unconditionally
   8     if musl is used. This should be a no-op if SSP is disabled and seems to be
   9     the only reliable way of dealing with SSP over all packages due to the mess
  10     that is linkerflags handling in packages.
