Remove exploitable LD_BIND_NOW hack (CVE-2009-1894).
Instead of trying to re-execute pulseaudio itself with LD_BIND_NOW set,
just find the correct flag for the linker to request immediate bindings
(all ELF files support that option), and use that when linking the daemon.
Reduce the amount of compiled and executed code as well.
