commit: https://git.buildroot.net/buildroot/commit/?id=c6cd512fe2e954b2ccc0412717c1c3380bc5f69b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
