This was always the intended behavior: when --embedded-variant is not

not link against unneeded libraries (only Clang). For deployment of

The reason for the compilation error is a mismatch of "V8_NOEXCEPT"

This is a false positive of a potential evaluation order problem flagged
by the newest version of gcmole. While this is strictly speaking safe,
it is not statically known that the default argument of the fourth
parameter to {AbsoluteAndNot} is a nullptr and hence not a stale raw
reference. Since this is the only false positive of this kind in the
code base, I would vote to just avoid it by sequencing the operations.
