[SCM] libav/experimental: configure: add --enable-pic flag

[siretart at users.alioth.debian.org]

The following commit has been merged in the experimental branch:
commit 8a3c86277bf77ee14ea04ec97c30a7689beff25d
Author: Måns Rullgård <mans at mansr.com>
Date:   Thu Aug 20 01:06:18 2009 +0000

    configure: add --enable-pic flag
    
    Using this flag enables position-independent code even when not strictly
    required.  It is impossible to use --disable-pic to forcibly disable PIC
    when other properties mandate it.
