[pacman-dev] [PATCH 1/2] libmakepkg/lint_pkgbuild: fix regression in linting depends=(foo=$pkgver-$pkgrel)

[Eli Schwartz]

In commit 91b72cc386ca03241791748da5da2b150c724ace support was added for
linting depends/etc. to ensure they contain only valid dependency
specifiers. However it did not properly take into account the
possibility of dependencies linked to a specific pkgrel, which promptly
failed to build because "-" is not allowed in a pkgver.

This is something supported by pacman and useful for e.g. split packages
which cannot be mismatched even if the pkgver is the same. Fix by
removing an optional suffixed "-$decimal" when checking for a valid
pkgver.
