[DragonFlyBSD - Bug #2559] gcc -pie and __builtin_popcount causes

[John Marino via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2559 has been updated by marino.


Using your program, I see the same error with:
* system gcc 4.4
* dports gcc-aux version 4.7

The latter is particularly telling because it's built with vendor makefiles.
Which means it's not a compiler problem but more likely a crt* stuff problem.

I found that __builtin_popcount is not usable with -pie option for gcc.
