missing byteorder

[fperrad]

BuildRoot just switched on Perl 5.20.1 & perl-cross 0.9.2.
Our autobuilders (http://autobuild.buildroot.org/?reason=perl-5.20.1) report many failures on big endian architecture.

../../config.h:982:19: error: invalid suffix "x" on integer constant
 #define BYTEORDER 0x /* large digits for MSB */
                   ^
../../perl.h:3477:30: note: in expansion of macro `BYTEORDER`
 #elif BYTEORDER == 0x4321 || BYTEORDER == 0x87654321
                              ^
In file included from DynaLoader.xs:122:0:
../../perl.h:3486:4: error: #error "Unsupported byteorder"
 #  error "Unsupported byteorder"
    ^

I found this workaround http://patchwork.ozlabs.org/patch/396615/

Hinting is definitely ok in this case, either multiarch or byteorder. The test I put there is rather fragile.

However, it did work, and I assume it worked for 5.20.0.
Looking at the problem now, chances are it can be fixed without using explicit hints.

Ok, fixed I think, at least for powerpc.
Turns out its data section is named .sdata instead of .data

[arsv]

Checked nios, same problem there. So the fix should work for both.

[fperrad]

Tested with powerpc.

It works now. Thanks

Ok, that's good. Tagged it as 0.9.3, along with perl version change to 5.20.1.
