[vlc-devel] [PATCH] contrib: Fix ARMv6 compilation

The contrib flags got messed up in d61052a0987d751ecda0b763c900f834f3358612. This led to VFP instructions being used on non-NEON devices, which led to many painful days of the following nonsense:

I/DEBUG   (  954): signal 4 (SIGILL), fault addr 42387d94
 The vlc-android counterpart is already made and will land soon, after some issues are resolved.

 This might look like a small fix but please do not underestimate the amount of debugging needed to get here.
