   1 We link to it unconditionally, as otherwise we get link failures if
   2 some objects are -fstack-protector built and final link happens with
   3 -fno-stack-protector. This seems to be the common case when
   4 bootstrapping gcc, the piepatches do not seem to fully fix the
   5 crosstoolchain and  bootstrap sequence wrt. stack-protector flag usage.

   7 Based on patch by Timo Teras for Alpine Linux.
