## This symbol is defined in libc++abi.tbd, but we are linking test.o against
## libc++.tbd (which re-exports libc++abi). Linking against this symbol verifies
## that .tbd file re-exports can refer not just to TAPI documents within the
## same .tbd file, but to other on-disk files as well.

## This tests that we can locate a symbol re-exported by a child of a TAPI
