[Buildroot] ldconfig - unknown machine 40

[Matthias 'muh' Pauligk <paulms@idmt.fraunhofer.de>]

Hi,

I faced the same problem using buildroot's toolchain.
The ld-config is present in the host directory, but the Makefile is looking
at the wrong path.
So I made a small patch to fix this issue, which is working fine for me:

        else \
                /sbin/ldconfig -r $(TARGET_DIR); \
        fi


Just apply it in buildroot's root directory. 
Maybe this is also working for external toolchains, depending on where
ld-config is located there.

Best regards.
