[PATCH] scripts: kconfig: merge_config.sh: create tmp file for awk

Posted by Mikko Rapeli 4 weeks, 1 day ago

From: Nathan Chancellor <nathan@kernel.org>

For some reason some awk versions/configurations fail to create
this output file. Create it in the shell script part before
providing it to awk.

Closes: https://lore.kernel.org/linux-kbuild/acb36651-449a-43e4-afe2-ba42a435cbb0@gaisler.com/
Fixes: 5fa9b82cbcfc ("scripts: kconfig: merge_config.sh: refactor from shell/sed/grep to awk")

Even though it is a bigger patch, I think I prefer Daniel's submitted
fix for this issue:
