[arch-general] Sha256sum unexpected behaviour

I got a weird issue with sha256sum behaviour. When creating the package
with makepkg --geninteg I get a hash and when trying to build it with
makepkg the hash fails. The interesting bit is --ptintsrcinfo comes up
with a different hash.

Anyone got some idea why this might happen?

See below some debugging info
