makepkg: deal with overriden package arch properly

This fixes a lot of checks done by makepkg (e.g. to see if a package
is already built and choosing which package to install).  Previously,
if a package had both "i686" and "any" versions, the "i686" one
always took precidence regardless of the value of "arch" in the
PKGBUILD for that package.  Fixes FS#27204.
