+Author: Timo Teräs <timo.teras@iki.fi>
+
+Alpine musl package provides libssp_nonshared.a. We link to it unconditionally,
+as otherwise we get link failures if some objects are -fstack-protector built
+and final link happens with -fno-stack-protector. This seems to be the common
+case when bootstrapping gcc, the piepatches do not seem to fully fix the
+crosstoolchain and  bootstrap sequence wrt. stack-protector flag usage.
