+    <p>We also do not support using the distribution toolchain (i.e
+    the gcc/binutils/C library installed by your distribution) as the
+    toolchain to build software for the target. This is because your

+    the C/C++ library), so we cannot import it properly into the
+    Buildroot build environment. So even if you are building a system

+    cross-compilation toolchain with Buildroot or Crosstool-NG.</p>
