Allow disabling PIE for dynamically linked executables

arm: Allow disabling PIE for dynamically linked executables

PIE can and does break some binaries that were built without it,
resulting in relocation-related issues (addressing memory
wrongly assumed to be at a fixed position).

Use this as a last resort measure for compatibility with pre-JB
binary blobs, and only if confirmed to fix a broken executable.
If you're not sure, do NOT enable this on a device.

arm: Drop linker script when building without PIE

The current section headers generated by bionic are incompatible
with this (interp is in, ctors were dropped, and other tiny changes
related to Elf32_Dyn). But... we don't actually need this to
disable PIE, so drop it entirely instead of writing a new one.
