[Buildroot] [PATCH v5 4/4] Revert "package/sdl2: disable altivec built-in function for PowerPC"

[Romain Naour <romain.naour@gmail.com>]

The bug discover while packaging supertux is now fixed by the previous
patch but the issue can still be present in other C++11 package if
-std=c++11 is used on PPC with Altivec vectorization.

This reverts commit d2903aaf1314b50a8a10ce937d2b33c5c42e463e.
