populate_sdk_base: Add ld.so.conf for nativesdk-binutils

Extend the functionality provided by commit [1] to the SDK as well. This way we
can make sure that nativesdk-binutils finds SDK libraries first rather than
host ones.

This is useful for example when trying to build the linux kernel using
nativesdk-gcc. This scenario currently fails because it tries to link to host
libraries rather than SDK host ones:

make x86_64_defconfig
make bzImage
...
error: Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel
Makefile:1101: recipe for target 'prepare-objtool' failed
make: *** [prepare-objtool] Error 1
....
/../../../../x86_64-wrlinuxsdk-linux/bin/ld: /lib/x86_64-linux-gnu/libpthread.so.0: undefined reference to `__libc_vfork@GLIBC_PRIVATE'
...
