RISC-V: Define MUSL_DYNAMIC_LINKER
Use no suffix at all in the musl dynamic linker name for hard
float ABI. Use -sf and -sp suffixes in musl dynamic linker name
for soft float and single precision ABIs. The following table
outlines the musl interpreter names for the RISC-V ABI names.
musl interpreter | RISC-V ABI
----------------------- | -------------
ld-musl-riscv32.so.1 | riscv32-ilp32d
ld-musl-riscv64.so.1 | riscv64-lp64d
ld-musl-riscv32-sf.so.1 | riscv32-ilp32
ld-musl-riscv64-sf.so.1 | riscv64-lp64
ld-musl-riscv32-sp.so.1 | riscv32-ilp32f
ld-musl-riscv64-sp.so.1 | riscv64-lp64f
