[PATCH] kbuild: dummy-tools: adjust to scripts/cc-version.sh

[Masahiro Yamada]

Commit aec6c60a01d3 ("kbuild: check the minimum compiler version in
Kconfig") changed how the script detects the compiler version.

Get 'make CROSS_COMPILE=scripts/dummy-tools/' back working again.

Fixes: aec6c60a01d3 ("kbuild: check the minimum compiler version in Kconfig")

Perhaps, Jiri may have already noticed this issue, and have a similar patch.
I just checked ML, but I did not find a patch to fix this.
