Respect the `--enable-version-specific-runtime-libs' configuration option in libada/, so that shared gnatlib libraries will be installed in non-version-specific $(toolexeclibdir) if requested. In a cross-compilation environment this helps setting up a consistent sysroot, which can then be shared between the host and the target system.
Update the settings of $(toolexecdir) and $(toolexeclibdir), unused till now, to keep the current arrangement in the version-specific case and make the new option to be enabled by default, unlike with the other target libraries, so as to keep existing people's build infrastructure unaffected. Of course if someone does use `--disable-version-specific-runtime-libs' already, then the installation location of shared gnatlib libraries will change, but presumably this is what they do want anyway as the current situation where the option is ignored in libada/ only is an anomaly really rather than one that is expected or desired. gcc/ada/ * gcc-interface/Makefile.in (ADA_RTL_DSO_DIR): New variable. (install-gnatlib): Use it in place of ADA_RTL_OBJ_DIR for shared library installation. libada/ * Makefile.in (toolexecdir, toolexeclibdir): New variables. (LIBADA_FLAGS_TO_PASS): Add `toolexeclibdir'. * configure.ac: Add `--enable-version-specific-runtime-libs'.
