Enabling the SPDX class and running two builds, one with SDKMACHINE=i686
and then again with SDKMACHINE=x86_64 would lead to errors since the output
was stored per MACHINE and the overlapping files would cause manifest errors.
The hashfn data from bitbake has SSTATE_PKGARCH encoded into it which is how
sstate separates out it's targets and SDPX should be using the same structure.
Therefore switch to using this.
