ASan and TSan are useful debugging tools, enable them on the
target and add the packages to packagegroup-core-sdk.

Gah. It works for x86_64 too, so RUNTTIMETARGET there should also have
libsanitizer

I get the following error during do_install for gcc-runtime on Arch
Linux x86_64 host when it is linking libasan:
/usr/lib/libpthread.a: error adding symbols: File format not recognized

What machine are you building for? Or is this the SDK that's failing?
This error looks like it's trying to link against the host's pthread library.
I tested this on Fedora 20 x86_64.

I am building for ARMv7 device. I tested your v3 "gcc-runtime: enable
sanitizer" patch as well with the same result (bitbake gcc-runtime).
It is same issue as posted on opemembedded-devel some months ago:
http://permalink.gmane.org/gmane.comp.handhelds.openembedded/63689
When running do_install for gcc-runtime, it relinks libasan and has
-L/usr/lib in the command line when linking libasan.so because
libasan.la contains:
libdir='/usr/lib'.
The log.do_install file indicates:
warning: library search path "/usr/lib" is unsafe for cross-compilation
On your host system, do you have /usr/lib/libpthread.a?
Does your log.do_install indicate the that libasan.so is linked with
-L/usr/lib search path with "warning: library search path "/usr/lib" is
unsafe for cross-compilation"?

Jonathan

I'm not getting the QA warning. I'm not sure why; in my logs I'm
seeing that it's trying to use /usr/lib,
but ld continues on its merry way after it finds the real library in
the sysroot. I'm noting two problems with my change:
1) gcc-runtime now depends on glibc being in the sysroot
and
2) libsanitizer insists on using adding -L/usr/lib to the link
command. It seems to be because it uses libstc++'s .la file that was
just built AND the one installed already.
I wonder what happens if libsanitizer gets installed before libstdc++.
