We do this kind of thing by using 'packaged-staging':

- compile the toolchain once on one computer (e.g. 'bitbake meta-toolchain')
- copy the resulting staging dir ( ${PSTAGE_DIR} )
 somewhere ( e.g. http://server/pstage )
- Set PSTAGE_MIRROR in your local.conf (e.g. PSTAGE_MIRROR = http://server/pstage/ )

When then  building on another computer, pre-built packages will be fetched from PSTAGE_MIRROR and not rebuilt. This will drastically speed up build times.

Note: if you want to use local URIs for PSTAGE_MIRROR (e.g.: file://xxx), you will need following patch, which has been acked but not merged upstream yet:
