scripts: correctly warn when the local tarballs directory does not exist
Warn about a missing local tarball directory, only if it was configured.
Avoid the spurious message:
Directory '${CT_LOCAL_TARBALLS_DIR}' does not exist.
Will not save downloaded tarballs to local storage.
Thanks to "Pedro I. Sanchez" <psanchez@colcan.ca> for pointing out the
issue:

3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g.,
4 MPC8548, MPC8572). It uses eglibc (for e500/SPE patches) and a recent
5 gcc (4.3.1, for e500v2 DPFP support) and will generate appropriate
6 dual-precision floating point instructions by default.
8 Note: If building a Linux kernel with this toolchain, you will want to
9 make sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE
10 ABI/instructions from getting into the kernel (which is currently
11 unsupported). At this time, the kernel build system only passes
12 -mno-spe by default (this should be fixed soon hopefully)."
