Masahiro Yamada 23d3f191a5 kbuild: remove *.tmp file when filechk fails
[ Upstream commit 88fe89a47153facd8cb2d06d5c8727f7224c43c2 ]

Bartosz Golaszewski reports that when "make {menu,n,g,x}config" fails
due to missing packages, a temporary file is left over, which is not
ignored by git.

For example, if GTK+ is not installed:

  $ make gconfig
  *
  * Unable to find the GTK+ installation. Please make sure that
  * the GTK+ 2.0 development package is correctly installed.
  * You need gtk+-2.0 gmodule-2.0 libglade-2.0
  *
  scripts/kconfig/Makefile:208: recipe for target 'scripts/kconfig/gconf-cfg' failed
  make[1]: *** [scripts/kconfig/gconf-cfg] Error 1
  Makefile:567: recipe for target 'gconfig' failed
  make: *** [gconfig] Error 2
  $ git status
  HEAD detached at v5.4
  Untracked files:
    (use "git add <file>..." to include in what will be committed)

          scripts/kconfig/gconf-cfg.tmp

  nothing added to commit but untracked files present (use "git add" to track)

This is because the check scripts are run with filechk, which misses
to clean up the temporary file on failure.

When the line

  { $(filechk_$(1)); } > $@.tmp;

... fails, it exits immediately due to the 'set -e'. Use trap to make
sure to delete the temporary file on exit.

For extra safety, I replaced $@.tmp with $(dot-target).tmp to make it
a hidden file.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
