Add a shell script that generates the ARM trampoline page. This generates a page of 340 trampolines, aligned within one page. The trampolines use pc-relative addressing to reference config data (context, jump address) from a page placed directly prior to the trampoline page. This can be used on systems -- such as iOS -- that do not support writable, executable memory by remapping the executable page containing the trampolines directly above a newly allocated writable config page.
