libc6-dev installs dangling symlink /usr/lib/i386-linux-gnu/libnss_db.so

[Rolf Leggewie]

[Impact / Justification]
While probably mostly cosmetic (how often do people link directly to NSS modules anyway?), shipping a -dev symlink to a non-existent library is poor form, at best, and could potentially break or confuse some esoteric build system at worst.

[Test Case]
debdiff the old and new libc6-dev to note that the offending symlink is no longer shipped.

[Regression Potential]
Very low. Just removing a single symlink to nowhere.

[Original Report]
The package libc6-dev in precise installs a dangling symlink.

$ ll /usr/lib/i386-linux-gnu/libnss_db.so
lrwxrwxrwx 1 root root 34 Okt 5 22:40 /usr/lib/i386-linux-gnu/libnss_db.so -> /lib/i386-linux-gnu/libnss_db.so.2
$ ll /lib/i386-linux-gnu/libnss_db.so.2
ls: cannot access /lib/i386-linux-gnu/libnss_db.so.2: No such file or directory
$ dpkg -S /usr/lib/i386-linux-gnu/libnss_db.so
libc6-dev: /usr/lib/i386-linux-gnu/libnss_db.so

This doesn't affect 2.16/2.17 in raring, only 2.15 in precise/quantal.

This bug was fixed in the package eglibc - 2.15-0ubuntu10.4

---------------
eglibc (2.15-0ubuntu10.4) precise; urgency=low

  * Add patch ubuntu/local-disable-nscd-netgroup-caching.diff to
    disable netgroup caching in the default config (LP: #1068889)
  * Backport any/cvs-malloc-deadlock.diff from upstream to prevent
    glibc deadlocking in mallock arena retry paths (LP: #1081734)
  * Fix futex issue (BZ #13844), backport from 2.16 (LP: #1091186)
  * Drop patch any/local-disable-nscd-host-caching.diff, as this
    bug was apparently resolved upstream a while ago (LP: #613662)
  * Add patch any/cvs-ld-self-load.diff to restore ld.so's ability
    to load itself, a behaviour accidentally removed (LP: #1088677)
  * Drop dangling libnss_db.so symlink in libc6-dev (LP: #1088773)
