Subject: [PATCH] Disable branch-patching

This patch disables JamVM's branch-patching optimization, which tends
to make JamVM fail with an "Illegal instruction" error on x86_64 (and
possibly other architectures that use variable-length instructions)
when built using modern versions of gcc and glibc.
