gcc has some code sanitizer features, which are currently neither built nor packaged so far as I know, but it might be nice to add support for them. (Noticed because one of our binary toolchains has the libraries, but nothing packages them yet.)
There's a patch on the list (http://patchwork.openembedded.org/patch/80369/) that adds a libsanitizer recipe, which packages: /usr/lib/libasan.so.1.0.0 /usr/lib/liblsan.so.0.0.0 /usr/lib/libtsan.so.0.0.0 /usr/lib/libubsan.so.0.0.0 Is this everything you wanted?
The patch was merged as of 1709bf0c3a84bb04bc52e9104ad8e09fba6c6f91.
