+                 This enables package build as Position Independent Executables (PIE)
+                 to protect against "return-to-text" attacks. This belongs to the
+                 feature of Address Space Layout Randomisation (ASLR), which is
+                 implemented by the kernel and the ELF loader by randomising the
+                 location of memory allocations. This makes memory addresses harder
+                 to predict when an attacker is attempting a memory-corruption exploit.
+                 You can disable this per package by adding PKG_ASLR_PIE:=0 in the package
+                 Makefile.
