If the library is run on a machine that is not the target machine, the
there are some support codes that depends on the host (the running machine)
and the target (the simulated machine).

Assume a 32-bit machine on which a double and a long long are 64 bits
wide -- thus implemented as two words aggregates. The issue
is what is the "order of the words" in a double (floating-point
word-order) and in a long long (integral-type word order).
