Bug 701996 broke elfhack, and elfhack was disabled as a result. Bug 703305 fixed elfhack, so we should re-enable it. Especially considering this:
11-23 19:57:42.208 E/GeckoLibLoad( 9085): Loaded libs in 1268ms total, 742ms user, 183ms system, 13 faults
11-23 19:57:42.208 E/GeckoLibLoad( 9085): Spent 273ms on relocations, 3ms on constructors
With elfhack, relocations time goes near 0, and constructors time stays under 30ms (iirc). It also makes the mount of data to uncompress smaller, which means faster decompression.
A nightly with elfhack enabled, on the same device, loads libraries under 900ms.

Better with elfhack :)
E/GeckoLibLoad(25781): Loaded libs in 910ms total, 472ms user, 152ms system, 2 faults

I didn't mean to reopen the bug. Sorry.
