Reversed byte order issue with nft ?

[leroy christophe <christophe.leroy@xxxxxx>]

Hi,

When doing 'nft list ruleset', I get a bad result (see below), fields 
appear as "unknown" and/or as numeric values.

Running 'nft' with gdb, it looks like something is wrong with byte ordering:

In function symbolic_constant_print(), mpz_export_data() return a 
strange val.
First time we go there, we get 0x800000000
Next time, we get 0x400000000
Last time, we get 0x200000000
While we expect 8(new), 4(related), 2(established)

Any idea on what to do ?

Target is a powerpc (big endian), everything is cross-compiled using GNU 
tools on x86 (little endian)

kernel 3.18-rc7
nftables-20141121
libnftnl-20141121
gmp-4.3.2
libmnl-1.0.3
libnfnetlink-1.0.1
libnetfilter_conntrack-1.0.4

Thanks
Christophe
