The golang package is generated only for i386, amd64, armel, armhf and
kfreebsd-* architectures, because of upstream restrictions.
Quoting from upstream documentation (http://golang.org/doc/install.html):
The Go compilers support three instruction sets. There are
important differences in the quality of the compilers for the
different architectures.
amd64 (a.k.a. x86-64); 6g,6l,6c,6a
The most mature implementation. The compiler has an effective
optimizer (registerizer) and generates good code (although
gccgo can do noticeably better sometimes).
386 (a.k.a. x86 or x86-32); 8g,8l,8c,8a
Comparable to the amd64 port.
arm (a.k.a. ARM); 5g,5l,5c,5a
Incomplete. It only supports Linux binaries, the optimizer is
incomplete, and floating point uses the VFP unit. However, all
tests pass. Work on the optimizer is continuing. Tested
against a Nexus One.
Except for things like low-level operating system interface code,
the run-time support is the same in all ports and includes a
mark-and-sweep garbage collector (a fancier one is in the works),
efficient array and string slicing, support for segmented stacks,
and a strong goroutine implementation.
The compilers can target the FreeBSD, Linux, and OS X
(a.k.a. Darwin) operating systems.
