This will allow to pass the -dbcache option to bitcoind, which is expected to speedup IBD on machines with larger memory capacity.
On a machine with at least 16GB of RAM:
export ABC_BUILD_NAME=build-ibd export IBD_BITCOIND_EXTRA_ARGS="-dbcache=15000" ./contrib/teamcity/build-configurations.sh
export ABC_BUILD_NAME=build-ibd ./contrib/teamcity/build-configurations.sh

It does looks like these args are only passed down to IBD, not bitcoind in general. For instance, they do not get passed down integration tests.
