gcc: Fix compilation error in core C gcc compiler older than v5

Browse Source 
When core gcc older than v5 is compiled it shows the error message:

Build failed in step 'Installing core C gcc compiler'
      called in step '(top-level)'

Error happened in: CT_DoExecLog[scripts/functions@376]
      called from: do_gcc_core_backend[scripts/build/cc/gcc.sh@627]
      called from: do_cc_core[scripts/build/cc/gcc.sh@210]
      called from: main[scripts/crosstool-NG.sh@697]

configure: error: in
`.../build/build-cc-gcc-core/fixincludes':
configure: error: C compiler cannot create executables

This patch disable `all-build-libcpp' target when core gcc
older than v5 is configured.
