Subject: bug#51559: [PATCH v2] gnu: webkit: Disable SSE2 when not on x86_64.
Date: Sat, 6 Nov 2021 09:21:02 +0100

* gnu/packages/webkit.scm (webkitgtk)[#:phases]: Add ‘disable-sse2’ if the
current (target) system is not an x86_64 one.
---
Hi Maxime,

I tried conditionally disabling SSE2 on the host side, but for some reason this
patch would cause a rebuild for me.  Did I do something wrong?
