Subject: [PATCH 1/9] kunit: tool: Enable CONFIG_FORTIFY_SOURCE under UML

From: Kees Cook <[email protected]>

Since commit ba38961a069b ("um: Enable FORTIFY_SOURCE"), it's possible
to run the FORTIFY tests under UML. Enable CONFIG_FORTIFY_SOURCE when
running with --altests to gain additional coverage, and by default under
UML.

Hah oops. Wrong From/SoB. That's what I get for writing this on a plane.
