[PATCH 2/2] libada: Respect `--enable-version-specific-runtime-libs'

Can you clarify what will be the value of ADA_RTL_OBJ_DIR and ADA_RTL_DSO_DIR
in the following cases:

- no version-specific-runtime-libs configure switch at all (default)
- use of --enable-version-specific-runtime-libs
- use of --disable-version-specific-runtime-libs
