CMAKE: fixed cflags check for build type

If there is a variable named test, then cmake does variable-value comparison:
if (test STREQUAL "")
is equivalent to:
if ("${test}" STREQUAL "")

If there is no variable named test, then cmake does string literal comparison:
if (test STREQUAL "")
is equivalent to:
if ("test" STREQUAL "")

That means basically - the current stuff works - but is not how it should be done.

Fixes https://github.com/libsdl-org/SDL/issues/2100
