[Buildroot] [PATCH] glibc: install glibc utils to target

With this patch we introduce an option for glibc, which
installs getconf, ldconfig and ldd utilities on target, that
may be useful in debugging. By default these utilities are
built, but not installed to the target.
ldd is a bash script, so it has bash dependency.
