[committed] d: Predefine the D_PIE version condition when flag_pie is set.

[Iain Buclaw via Gcc-patches]

Hi,

This patch adds D_PIE to the list of predefined version conditions when
flag_pie is default, or set by the command-line.  Same as the D_PIC
version condition.

Bootstrapped and regression tested on x86_64-linux-gnu/-m32/-mx32, and
committed to mainline.

Regards,
Iain.
