[Buildroot] [PATCHv4 02/16] core: enable 'NDEBUG' unless BR2_ENABLE_RUNTIME_DEBUG is set

From: Thomas De Schampheleire <thomas.de_schampheleire at nokia.com>

The 'assert' statement in glibc honors the 'NDEBUG' preprocessor macro: if
it is set, then the assert statement is compiled away.

Define this 'NDEBUG' macro when BR2_ENABLE_RUNTIME_DEBUG is disabled (the
default case).

v4: reintroduced patch on suggestion of Arnout. I had previously dropped it from
the series based on an incorrect conclusion.
