Initial Package Version: 1.7.11
Origin: Upstream HG
Upstream Status: In HG
Description: When PAM is not installed, sudo may use shadow passwords. The
             released version unconditionally links to libshadow in this case,
             while -lshadow is only needed for some linux distros, and is
             not available for LFS.

Only check for -lshadow if we haven't already found getspnam() in
libc.  Rather than treat this specially, just add -lshadow as another
place to search in addition to -lgen.
