This is due to an OpenBSD specific GCC bounds checker.

     -   gcc recognizes a new flag, -Wbounded, to perform basic checks
         on functions which accept buffers and sizes.  An extra
         attribute, __bounded__, has been added to mark functions that
         can be checked this way.

There was another issue here..

  CC    hw/display/exynos4210_fimd.o
hw/display/exynos4210_fimd.c: In function 'exynos4210_fimd_reset':
hw/display/exynos4210_fimd.c:1342: warning: array size (16) smaller than 
bound length (192)
hw/display/exynos4210_fimd.c:1342: warning: array size (16) smaller than 
bound length (192)
