fedora and opensuse derived distros call it systemtap-sdt-devel,
debian derived distros call it systemtap-sdt-dev.

At least those derived from fedora, opensuse and debian.

I don't think it has any requirements.

I think the package is architecture all since the only architecture
specific thing there possibly could be is whether the NOP instruction is
called NOP. But I know people have been using it at least on amd64,
armel, i386, ia64, powerpc and s390.

I wouldn't bother, in general sys/sdt.h should be universally available.
And it has some tricks to be more efficient if the assembler contains
the right support for certain directives, so you would then also need to
add the configury for sdt-config.h.in if you are going to install it
yourself.
