makepkg: allow overriding arch in split packages

This allows building a mixture of binary and arch=any packages.
Fixes FS#15955.

The value of CARCH is no longer overridden to "any" in when arch=any
is used and the assigning of the "any" arch is delayed to during the
packaging stage. Adjustments were required to fix installing and
checking for pre-built packages of varing arches.

 All options and directives for the split packages default to the global values given
 within the PKGBUILD. However, some of these can be overridden within each split
 package's packaging function. The following variables can be overridden: `pkgver`,
