[pacman-dev] pacman-5.0:error run updpkgsums when there is source_i686 or source_x86_64 in PKGBUILD

[Zuyi Hu]

I am using the pacman's latest master branch,When I run updpkgsums when
there is source_i686 or source_x86_64 in PKGBUILD. it will complain:
/usr/share/makepkg/lint_pkgbuild/variable.sh: line 60: declare: sha512sums:
not found
==> ERROR: sha512sums_i686 should be an array
/usr/share/makepkg/lint_pkgbuild/variable.sh: line 60: declare: source: not
found
==> ERROR: source_i686 should be an array
/usr/share/makepkg/lint_pkgbuild/variable.sh: line 60: declare: sha512sums:
not found
==> ERROR: sha512sums_x86_64 should be an array
/usr/share/makepkg/lint_pkgbuild/variable.sh: line 60: declare: source: not
found
==> ERROR: source_x86_64 should be an array
==> ERROR: Failed to generate new checksums

for example, you can use nvidia's PKGBUILD in extra repo, and try run
updpkgsums.

I think this bug is introduced by this commit:
https://projects.archlinux.org/pacman.git/commit/?id=23f128ad5e2b26733376d16f5095d36085a97747

a simple workaround patch is:
