dl06 fails to build for RISC-V (griscv bsp)

[Hesham Almatary]

I have only made sure rap builds when I added libdl support for
RISC-V. But I haven't tested it on run-time, only ELF objects. It's
likely to have been failing in run-time all along. Also, there are a
few relocations still to be implemented for ELF like PCREL_LO12_X and
RELAX. I got around that by passing -mno-relax
