ghc doesn't find libffi.so.5 in testsuite

Running the testsuite, more or less every dyn test fails with

Wrong exit code (expected 0 , actual 127 )
Stdout:

Stderr:
./T5041: error while loading shared libraries: libffi.so.5: cannot open shared object file: No such file or directory

(some fail for other reasons before getting to that stage).

Running make TEST=whichever in the testsuite directory, all the tests I tried passed the dyn way, so it seems to be an issue with the testsuite-driver.
