Make ksu work when unsetenv() returns NULL
Some older platforms (OS X 10.4, glibc 2.2.1) declare unsetenv() as
returning void, as does ksu's compatibility definition of unsetenv().
Don't use the return value in get_configured_defccname().
(cherry picked from commit 7eee546db10e907666e02fdded4f512e8d0faf4c)
