Fixed bug 4103 - SDL_cpuinfo.h provokes warnings with -Wundef on non-x86 hosts 

Felix Geyer

Forwarding from https://bugs.debian.org/892087 quoting verbatim:

The SDL2 header SDL_cpuinfo.h generates gcc warnings if the program using
it compiles with the -Wundef warning. (In particular, this means that QEMU
builds using it fail on at least sparc hosts, since QEMU dev builds
use both -Wundef and -Werror.).

/usr/include/SDL2/SDL_cpuinfo.h:63:5: warning: "HAVE_IMMINTRIN_H" is not defined, evaluates to 0 [-Wundef]
 #if HAVE_IMMINTRIN_H && !defined(SDL_DISABLE_IMMINTRIN_H)
