Followup to <http://issues.guix.gnu.org/issue/26175#4>:
guix shall print a hint if building fails due to the package source base
name containing a character invalid in a store filename (e.g. "@" or "%").
Currently, when building such a package, one gets an error message like:
guix build: error: invalid character `@' in name
`address@hidden'
guix build should catch this error and print a hint like:
You may add a ‘file-name’ field to the package source to work around this.

Example package raising this error:
(use-modules (guix packages) (guix download) (guix build-system gnu))
(package
(name "kde-l10n-ca-valencia")
(version "14.11.80")
(source
(origin
(method url-fetch)
(uri (string-append "mirror://kde//Attic/applications/"
version "/src/kde-l10n/"
"kde-l10n-ca@valencia-" version ".tar.xz"))
(sha256 (base32
"1mqadassxcm0m9r1l02m5vr4bbandn48xz8gifvxmb4wiz8i8d0w"))))
(build-system gnu-build-system)
(synopsis "") (description "") (license "") (home-page ""))
