commit: http://git.buildroot.net/buildroot/commit/?id=34f95bf9dbb0a2698d425975d83a92fa5e7ca0aa
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
The uClibc-ng dynamic loader is called ld-uClibc.so.1, but gcc is not
patched specifically for uClibc-ng, so it continues to generate
binaries that expect the dynamic loader to be named ld-uClibc.so.0,
like with the original uClibc.
Therefore, when a uClibc-ng toolchain is used as an external
toolchain, we need to create an additional symbolic link to make
uClibc-ng systems work properly.
