cmake.eclass: do not append -DNDEBUG to CPPFLAGS
The NDEBUG macro turns the assert() function into a noop. This gives a
small performance boost, but may allow subtle programming errors to go
unnoticed.
This code was added back in 2008, when we started passing
-DCMAKE_BUILD_TYPE=None instead of Release or Debug. It probably tries
to mimic a default behavior of Release type builds.
Other common build systems do not do this by default. For example,
autoconf's AC_HEADER_ASSERT macro only sets NDEBUG if --disable-assert
is passed to configure (it defaults to enabled).
It is better to let users add this to CPPFLAGS themselves if they really
want to save those few CPU cycles.
