[oe] [RFC] move to opkg / md5 error on big-endian machine

[Jeremy Lainé]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

opkg systematically fails to check the MD5 checksums on big-endian
targets. The reason for this is that md5.c was taken from glibc, and
it only sets the endianness correctly if _LIBC is defined:

#ifdef _LIBC
# include <endian.h>
# if __BYTE_ORDER == __BIG_ENDIAN
#  define WORDS_BIGENDIAN 1
# endif
[snip]
#endif

Attached is a patch thats sets WORDS_BIGENDIAN on big-endian machines
without touching the code, and fixes the MD5 errors I was getting.

Rather than putting this patch into OE, maybe we should push this
upstream?

Cheers,
