[guix-commits]

marusich pushed a commit to branch wip-ppc64le
in repository guix.

commit 1bc3feeb2b5484381138e4ab9fd1697da26f4dca

    tests: gremlin: Skip file-needed/recursive if DT_NEEDED is empty.
    
    * tests/gremlin.scm (file-needed/recursive): Skip the test when 
(file-runpath
    %guile-executable) evaluates to the empty list.  This fixes the test, which
    previously failed incorrectly in the case where Guix has been built using a
    foreign distro's toolchain and libraries.
