[sparc64] Fix build of games/vkquake

Build of sparc64 fails with:

gl_draw.c: In function 'Draw_PicFromWad2':
gl_draw.c:285: warning: array size (4) smaller than bound length (24)
gl_draw.c:285: warning: array size (4) smaller than bound length (24)
gl_draw.c: In function 'Draw_TryCachePic':
gl_draw.c:354: warning: array size (4) smaller than bound length (24)
gl_draw.c:354: warning: array size (4) smaller than bound length (24)
gl_draw.c: In function 'Draw_MakePic':

Since it has -Werror, those warnings kill it.

This patch drops -Werror and allows it to build on sparc64.

ok?
