Jitterentropy library must be built with compiler optimisation disabled
as it *relies* on this. The below change to the Makefile ensures that abuild
general settings do not override the -O0 setting in the Makefile.

This is an Alpine-specific change and so not submitted upstream - it was
however discussed with upstream:
