Does this need recompiling?

Is it a boot option only, or can it be done after the system is booted?

It's a sysctl setting that can be modified at run time. Mostly. Unless you set its value to "3", at which point it'll stick and can't be modified again. More information, as usual, in the kernel documentation: https://www.kernel.org/doc/Documentation/security/Yama.txt Mihai
