Hello,

Just a simple update, but sadly, I am unable to build using QEMU for other platforms. Same as with previous version, it does NOT build correctly on armhf.

It appears to be an false assumption of SSE2 support where there is none? In addition, the same error happens when building this new version on aarch64, but not the previous one. The package definition for gemmlowp might have a clue as to what to do here.

Since QEMU is a machine emulator/virtualizer, I'm not sure how relevant this is, but my machine's CPU does not have SSE2 itself, AFAIK.
