Negative subscripts to indexed arrays are not supported before 4.2. However,
since substring expansion works on arrays, we can specify an offset of -1 to
be taken relative to one greater than the maximum index of the specified
array (see Parameter Expansion section of the bash man page). This works with
both Bash 4.1 and 4.2, and 4.1 is already the oldest supported by pacman.

The return value was being assigned when an error was found in a PKGBUILD's
arch array but it never was returned.
Also remove error message explaining about adding the arch array to a PKGBUILD.
That was added a long time ago when the arch array first became compulsory.

When extracting variables from PKGBUILD (e.g. for .SRCINFO creation) we make
assumptions about whether variables are arrays or not. This adds a check to
the PKGBUILD linter to ensure variables are arrays or not as appropriate.

The check that pkgver is non-empty done in check_pkgver should also be
performed after running the pkgver() function. Merge validate_pkgver
into check_pkgver and run check_pkgver after updating pkgver.
