[Buildroot] [PATCH] uclibc: add simlinks from libdl/libm/libpthread/librt

[Paul Cercueil]

All the symbols that were previously present in libdl.so.0, libm.so.0,
libpthread.so.0 and librt.so.0 are now all packed within uClibc.

In order to keep binary compatibility with old executables, which were
dynamically linked with one of the libraries above, add symbolic links
to the uClibc shared library.
