[Buildroot] [PATCH 1/1] utils/test-pkg: Generate package config if it is not specified

[Vadim Kochan]

From: Vadim Kochan <vadim4j@gmail.com>

It is possible to generate one-line config for the package just by
normalize it to the form:

    BR2_PACKAGE_${pkg_replaced-to_and_uppercase}

it simplifes a bit of testing package where no additional config options
are needed.

 A race-free way of cleaning up! Excellent!

 The script is already using bash, so this is OK.

 However, the UPPERCASE macro also converts . to _. Still, since we don't have
any package with . in it, it should be fine.

Applied to master, thanks. I was initially a bit skeptical because if
the package has a dependency, your solution does not work very well,
and users could believe that the package is going to be tested while it
won't. But in fact in that case all tests are going to be "SKIPPED"
because the BR2_PACKAGE_FOO=y line is not in the final .config. This
will clearly tell the user that much not testing has happened. So I'm
fine with this, and therefore I applied.

Thanks!

Thomas

While this isn't a bugfix, it seems quite safe and can be useful for
users - So I've committed it to 2019.02.x as well, thanks.
