Creating a snap that will support many architectures require conditional ``configflags``. The grammar available for ``build-packages`` and ``stage-packages`` would be nice to also have for ``configflags``. (A side note is that the existing support for build/stage-packages could grow the ability to list multiple architectures so you don't have to repeat entries that are true for multiple archs) Mock-up that matches existing grammar for build/stage-packages: parts: qemu: plugin: autotools configflags: - on amd64: - --enable-xen - on i386: - --enable-xen Even better: parts: qemu: plugin: autotools configflags: ? - all : - "--enable-something-everywhere" ? - amd64 - i386 : - "--enable-xen"
