a01c5f8fd8 Add a conditional to enable retpoline support
Using retpoline in userland code that doesn't run arbitrary code is
questionable to start with.

Linux is also getting SPECTRE v2 userspace-to-userspace protection.

In addition, some platforms have a gcc version that advertises
support for retpolines, but the resulting binaries simply don't work
or cannot be linked.

So, do not enable this by default. Let builders choose if they
really want to enable this in their builds.

b3ba348d08 Provides explicit_memset supports/NetBSD.
Similar to explicit_bzero function is to defeat
compiler optimisation.
