+# Additional note: Now that DYNAMIC_GHC_PROGRAMS is enabled by
+# default, we no longer need to disable PaX ASLR because the RTS
+# linker is not used... except for ghc-iserv. The program is launched
+# when ghci is started with -fexternal-interpreter without
+# -dynamic. Its purpose is to run non-PIC code from a dynamically
+# linked ghci, and therefore still uses RTS linker. Also note that RTS
+# linker requires PaX mprotect to be disabled too. This means that
+# once the merge request mentioned above is merged to the upstream, we
+# can at least enable PaX mprotect and PaX ASLR for all the
+# executables except ghc-iserv and ghc-iserv-prof.
