ADA_RTL_OBJ_DIR=$(libsubdir)/adalib
ADA_RTL_DSO_DIR=$(libdir)/gcc/$(target_noncanonical)/$(version)$(MULTISUBDIR)/adalib
e.g. (no multilibs):
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/x86_64-linux-gnu/10.0.0/adalib
ADA_RTL_DSO_DIR=$(prefix)/lib/gcc/x86_64-linux-gnu/10.0.0/adalib
or (with multilibs):
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib32/ilp32/adalib
ADA_RTL_DSO_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib32/ilp32/adalib
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib32/ilp32d/adalib
ADA_RTL_DSO_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib32/ilp32d/adalib
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib64/lp64/adalib
ADA_RTL_DSO_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib64/lp64/adalib

Same as above.
> - use of --disable-version-specific-runtime-libs
ADA_RTL_OBJ_DIR=$(libsubdir)/adalib
ADA_RTL_DSO_DIR varies in Makefile as the multilib part is now set by
`configure' as with other target libraries, so with `x86_64-linux-gnu'
(native) I have:
ADA_RTL_DSO_DIR=$(libdir)/../lib64
and with `riscv64-linux-gnu' (cross) I have e.g.:
ADA_RTL_DSO_DIR=$(exec_prefix)/$(target_alias)/lib/../lib64/lp64d
and then specifically (no multilibs):
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/x86_64-linux-gnu/10.0.0/adalib
ADA_RTL_DSO_DIR=$(prefix)/lib64
or (with multilibs):
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib32/ilp32/adalib
ADA_RTL_DSO_DIR=$(prefix)/riscv64-linux-gnu/lib32/ilp32
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib32/ilp32d/adalib
ADA_RTL_DSO_DIR=$(prefix)/riscv64-linux-gnu/lib32/ilp32d
ADA_RTL_OBJ_DIR=$(prefix)/lib/gcc/riscv64-linux-gnu/10.0.0/lib64/lp64/adalib
ADA_RTL_DSO_DIR=$(prefix)/riscv64-linux-gnu/lib64/lp64
[...]
Notice that ADA_RTL_OBJ_DIR never changes with/without the use of this
configuration option (as expected).
Does it answer your question?
