Last time I bumped a Qt version, I was surprised that Buildroot hasn't
such a script and I wrote one too but definitely not as good as yours ! :-)

I tried your script on the 2018.02.x branch to bump Qt to 5.9.6. It
ended with the following error:

make: *** empty string invalid as file name.  Stop.

Also, some hashes have a '.', for example:

-sha256 fef48529a6fc2617a30d75d952cb327c6be341fd104154993922184b3b3b4da1
qtbase-opensource-src-5.6.3.tar.xz
+sha256 fef485.9a6fc2617a30d75.952cb327c6be341fd10415.993922184b3b3b4da1
qtbase-opensource-src-5.6.3.tar.xz

I think that because of the 2nd script in the following sed expression:

> +# First, update references to Qt version in .hash files
> +find package/qt5/ -name "*.hash" -exec \
> +sed -e "s,$CURRENT_QT5_VERSION,$QT5_VERSION,g" \
> +    -e "s,$CURRENT_QT5_VERSION_MAJOR,$QT5_VERSION_MAJOR,g" \
> +    -i {} \;
> +

$CURRENT_QT5_VERSION and $CURRENT_QT5_VERSION_MAJOR contains '.' that
makes sed match hashes containing '5[a-f0-9]9' sequences. You have to
escape the '.' character. I fix this like this:

sed -e "s,${CURRENT_QT5_VERSION//./\\.},$QT5_VERSION,g" \
    -e "s,${CURRENT_QT5_VERSION_MAJOR//./\\.},$QT5_VERSION_MAJOR,g" \
    -i {} \;

Best regards,
