[PATCH] LoongArch: Modify MUSL_DYNAMIC_LINKER.

[PATCH] LoongArch: Modify MUSL_DYNAMIC_LINKER.

[Lulu Cheng]

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 LoongArch64 ABI names.

musl interpreter            | LoongArch64 ABI
--------------------------- | -----------------
ld-musl-loongarch64.so.1    | loongarch64-lp64d
ld-musl-loongarch64-sp.so.1 | loongarch64-lp64f
ld-musl-loongarch64-sf.so.1 | loongarch64-lp64s

Re:[pushed and backport] [PATCH] LoongArch: Modify MUSL_DYNAMIC_LINKER.

[chenglulu]

pushed to r14-5601

backport to r13-8085 and r12-9995.

r12 and r13 simultaneously synchronized the patch that changed '/lib64' 
to '/lib'.
