Bugzilla Bug 132992

Compilation with LDFLAGS="-Wl,--as-needed" goes fine, but displays errors when
register-common-lisp-implementation is run.

SBCL also presents broken runtime behavior, like not finding internal packages
such as SB-POSIX.

I think the best solution is to filter the flag in the ebuild.

Thanks for the bug report.  I made the following change.  Please emerge --sync
and check that it works for you.

This is not the answer, the problem does not exist on amd64 and sbcl is fine
with  --as-needed, please revert the changes until such time emerge info is
posted.

Please post your emerge info and a build log.

I re-emerged the unpatched version. Relevant output:

Is really worth the effort?  From
http://www.gentoo.org/proj/en/qa/asneeded.xml:

  "The flag tells the linker to link in the produced binary only the libraries 
  containing symbols actually used by the binary itself. ...
  allows the linker to avoid linking extra libraries in a binary. This not only 
  improves startup times"

The SBCL runtime links to glibc and thats it.

Its not like you're loading some gnome app which pulls in several dozen deps. 
If you want to keep this bug open, please reassign it to something not
common-lisp@gentoo.org.

0.9.12 is not in the tree anymore. Reopen if issue persists for other versions
1.0.4 and up.

This is NOT FIXED since it's worked around in tree.

Stelian has said that he will look into this.
