Thanks to Eric Botcazou, this eliminates almost all of the remaining Ada
testsuite failures by adding a missing definition for the target specific
handling of function descriptors.
Tested with a native riscv64-linux bootstrap with Ada, and running the Ada
testsuite. There are only 4 failures left.
Committed.
