 This doesn't seem right to me.  Currently the list produced is as 
follows:

RTLDLIST="/lib/ld-linux-riscv64-lp64.so.1 /lib/ld-linux-riscv64-lp64d.so.1"

regardless of whether the ABI configured for has been lp64 or lp64d.  With 
this change in place the list becomes ABI specific and is:

RTLDLIST="/lib/ld-linux-riscv64-lp64.so.1 /lib/ld-linux-riscv64-lp64.so.1 /lib/ld-linux-riscv32-ilp32.so.1 /lib/ld-linux-riscv32-ilp32.so.1"

-- for the ilp32 or lp64 ABIs, and:

RTLDLIST="/lib/ld-linux-riscv64-lp64.so.1 /lib/ld-linux-riscv64-lp64d.so.1 /lib/ld-linux-riscv32-ilp32.so.1 /lib/ld-linux-riscv32-ilp32d.so.1"

-- for the ilp32d or lp64d ABIs.  Please look into it.
