[panda-users] Compilation issue

Checking the build.sh script again, I believe we don't properly check if
the specific build for LLVM exists. (readlink -f doesn't check for the last
path component)
Can you add the following before line 19 ("# Using PANDA LLVM.") of
qemu/build.sh and test again?
[ ! -d "$PANDA_LLVM" ] && echo "NO WAY" && exit 1
If it stops there, then you have LLVM but you probably made a debug build.
