Given that I was the one that suggested something that doesn't work
without properly trying it first - sorry about that, how about this one:

source_i686=("source1_i686.tar.gz" "source2_i686.tar.gz")
md5sums_i686=('md5sum1_i686' 'md5sum2_i686')
source_x86_64=("source1_x86_64.tar.gz" "source2_x86_64.tar.gz")
md5sums_x86_64=('md5sum1_x86_64' 'md5sum2_x86_64')

package() {
    local -n source="source_$CARCH"
    tarball="${source[1]}"
    echo "$tarball"
    tarball="${source[0]}"
    echo "$tarball"
}

CARCH=i686
package

CARCH=x86_64
package

No evals, but probably requires a quite recent bash version (no problem
for arch I suppose). The output should look like:

source2_i686.tar.gz
source1_i686.tar.gz
source2_x86_64.tar.gz
source1_x86_64.tar.gz

This means you can get any element of the source_{i686,x86_64} array at
will via the source variable, this might be useful if there is more than
one source in the array.
