`makerepropkg` has a hardcoded "x86_64", so fails to run on other [unofficial]
architectures, because it tries to use an x86_64-specific makepkg config, which
overrides CARCH=x86_64. I tried addressing it with this simple patch:

This half-works, but the arch derivates still needs to ship a custom `devtools`
package with their own `makepkg-$CARCH.conf`. Usually, the only thing that
really needs to be changed in the per-architecture custom makepkg.conf is CARCH
and CHOST.

This is still not ideal, and sounds like it could be refined further into
something simpler. The .BUILDINFO file specifies the devtools version
originally used, so that makerepropkg can download that specific version and
use the right makepkg.conf file for the rebuild.

It would be much simpler dump all variables from `makepkg.conf` into .BUILDINFO
at build-time, and use these directly when rebuilding to test reproducibility.
Instead of the package indicating the version of devtools contains its build
configuration, the package just includes the build configuration directly. This
removes one level of indirection. This approach would also allow checking the
reproducibility of packages that were built with slight different settings
(including those built by derivates/unofficial platforms).

Any thoughts on this?

Side note: the above patch might still have value if merged, at least in the short term.
