Bug#1050516: checkit-tiff: FTBFS on big-endian platforms

[Bastian Germann]

Source: checkit-tiff
Severity: serious
X-Debbugs-Cc: art1 at andreas-romeyke.de, oltmanns at zib.de

The new checkit-tiff upstream version 1.4.3 does not build on big-endian 
platforms. Note: it was updated from 0.4.2, so the issue is not 
necessarily only in 1.4.3. You can get logs at 
https://buildd.debian.org/status/package.php?p=checkit-tiff

The issue triggers multiple times on running the test suite and ends up:
"(HE)TIFF Header error, not a MAGIC BYTE for TIFF: 0x2a00"
