[bug#49898] [PATCH v4] gnu: Add spectre-meltdown-checker.

[phodina]

Hi Leo,

I've substituted most of the commands. The only commands at the moment are echo 
and printf. I haven't found regexp that would work as they are text is also 
used for variables.

Otherwise the rest of the commands should be covered.

* gnu/packages/linux.scm (spectre-meltdown-checker): New variable.
