Linux kernel versions newer than 5.3 require rsync in order to export
the UAPI headers. Commit f441a6bf ("linux: Add dependency on rsync for
Linux >= 5.3") attempted to address this with a check that runs when
crosstool-ng is built. That had the downside that if crosstool-ng was
built and packaged on a machine that had rsync then run on a machine
that didn't then the build would fail due to the missing rsync.
Conversely if the first machine didn't have rsync installed when
crosstool-ng was built then we would not offer newer kernel versions.
We can address this by checking for rsync when the toolchain
configuration is updated using some functionality in the newer Kconfig
that we've updated to previously.
Fixes #1940

If you are in doubt that installed headers are buggy, say 'Y'

here to have an extra check passed onto the headers.
