Description
Compilation with LTO enabled fails due to mismatching types in the XZ part of TokuDB, throwing the following errors.

Compiling with -Wno-error=lto-type-mismatch allows the compilation to complete. However due to the differing definitions, this might potentially lead to data-corrupting bugs (I have not investigated whether corruption is actually possible here, but until someone does, it should be assumed to be possible).
