Have you tried adding --build=?

If you type "file gentmap", what binary format is it?

Yes.  Apparently "--build=" just defaults to whatever "--host=" was
set to, so there is no difference.

  gentmap: ELF 32-bit LSB MIPS-I executable, MIPS, version 1 (SYSV),

This was obviously built for the target, not the host.
