The issue is that current deb packages are built with autotools, and apparently clang is required for asan now: https://llvm.org/bugs/show_bug.cgi?id=22757
I am experimenting with building with "AUTOCONF_BUILD=no" in debian/rules, so far I had to remove all but the BugPoint tests from silent-MCJIIT-tests.diff (my first build failed with "unexpected passes :). However each build takes a while so not sure if it fully works yet.
