clang/cmake: Fix clang cmake can't find libgcc, align with makefile

Browse Source 
makefile:
ifeq ($(CONFIG_BUILTIN_TOOLCHAIN),y)
  COMPILER_RT_LIB = $(shell $(CC) $(ARCHCPUFLAGS) --print-libgcc-file-name)
  ifeq ($(CONFIG_ARCH_TOOLCHAIN_CLANG),y)
    ifeq ($(wildcard $(COMPILER_RT_LIB)),)
      # if "--print-libgcc-file-name" unable to find the correct libgcc PATH
      # then go ahead and try "--print-file-name"
      COMPILER_RT_LIB := $(wildcard $(shell $(CC) $(ARCHCPUFLAGS) --print-file-name $(notdir $(COMPILER_RT_LIB))))
    endif
  endif
