mail/solid-pop3d: APOP not working for big endian machines

[Michael Warmuth]

Hello,

the flavor apop of solid-pop3d does not work on sparc64.

The problem is caused by failing detection of big
endianess in md5.c (Linux-specific?):
        #ifdef _LIBC
        #include <endian.h>
        #if __BYTE_ORDER == __BIG_ENDIAN
        #define WORDS_BIGENDIAN 1
        #endif
        #endif

Patch (tested on sparc64 and amd64) is attached.

Please comment.

Thanks,

Michael
