[PATCH stable 6.1 1/3] perf build: Conditionally define NDEBUG

[Florian Fainelli <florian.fainelli@broadcom.com>]

From: Ian Rogers <irogers@google.com>

commit 616b14b47a86d880ba21a363440f20f82152d8f2 upstream

When a build is done without DEBUG=1 then define NDEBUG. This will
compile out asserts and other debug code.
