opensc builds ok on 64-bit archs with llvm22, but fails on i386:

helpfully, DES_LONG is an unsigned long on i386, but an unsigned int
on other archs:

/usr/include/openssl/des.h:
 64 #ifndef DES_LONG
 65 /* XXX - typedef to unsigned int everywhere. */
 66 #ifdef __i386__
 67 #define DES_LONG unsigned long
 68 #else
 69 #define DES_LONG unsigned int
 70 #endif
 71 #endif

is this an appropriate fix for now?
