Just tar the contents of output/host. However, beware that right now
the SDK is not relocatable, so you'll have to install it to the exact
same location on other machines. In general, the default location in
output/host is not very nice, so you can use the BR2_HOST_DIR
configuration option to change where the host directory gets
stored, and therefore put it for example in /opt/buildroot-sdk/, and
then tar this.

Making the SDK relocatable is on our TODO list. There is a list of the
issues to fix and some possible solutions at

No, the Eclipse support is orthogonal to this. The Eclipse support will
only write one line to $HOME/.buildroot-eclipse.toolchains for each
Buildroot toolchain that has been built on the system, so that Eclipse
cna easily show the available toolchain when the Buildroot Eclipse
plug-in is installed.
