commit: http://git.buildroot.net/buildroot/commit/?id=044a0f2919911b00bb38d4f1c2e486799cd4d670
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When building with musl, the build fails with a conflicting type
qualifier error.

This is because musl defines stdout and stderr as const pointers
and RaspiVidYUV.c adds an extern declaration as normal pointers.

Since this declaration already comes in on the header (stdio.h),
there is no need to add an extern declaration, so removes it.

Fixes:
