It depends on much your pinky has acclimated to that posture & how much time you spend practicing & training it otherwise.   In the end, it might not be a problem at all.  Every individual brings their own unique finger topology & idiosyncrasies to the task of playing guitar.  I have relatively small hands, and as a consequence had to figure out some alternate ways to play certain chords & lines.  As long as you can fret the notes you need to to play the music you want, there's no problem.

In general, practice will make you fingers more agile for the task.  Just keep working on the fundamentals.  If you find you want or need some exercises to help change your pinky, these tutorials cover how to build finger strength & dexterity in general & with a special focus on the pinky.
