RISC-V multilib toolchain(github.com/riscv/riscv-gnu-toolchain.git) put
multi ld.so with different ABI under sysroot/lib:
sysroot/lib/ld-linux-riscv32-ilp32d.so.1
sysroot/lib/ld-linux-riscv32-ilp32.so.1
sysroot/lib/ld-linux-riscv64-lp64d.so.1
sysroot/lib/ld-linux-riscv64-lp64.so.1
Current buildroot script can't handle multi ld.so and report:
>>> toolchain-external-custom Copying external toolchain sysroot to staging...
/bin/bash: line 0: [: too many arguments
This patch try to get the exact name for ld.so and avoid multi ld.so check in
the script.
