Sure, simply don't select and packages and no file systems, then it
will only build the toolchain.

Yes, the BR output is in general not relocatable.

No problem, as long as you don't move the toolchain around. We often
build pure toolchains with STAGING_DIR set to something like
/opt/cross/${DATE}, which can then simply be added to the path and
used.
