On Solaris, uname -m returns i386, since it's compatible with i386 ISA
applications, even when running the 64-bit kernel.   (Not changing uname
output between 32-bit & 64-bit kernels was a design decision made when
Solaris first added 64-bit support for SPARC in the late 90's, to increase
binary compatibility with existing programs & shell scripts.)

Other utilities, like isainfo, return amd64 for the 64-bit API.
