Repeat the fix done by the CL https://chromium-review.googlesource.com/226093 as the new function iface_undefined introduced by https://chromium-review.googlesource.com/232368 removed it for the ep_undefined function. When calling the ep_undefined function, the linker was not considering it as a Thumb function and not setting the LSB in the address pointer. This was causing an exception at runtime.
