Fix CFLAGS and CXXFLAGS in RbConfig::CONFIG on FreeBSD and NetBSD/amd64.
* configure.in: Fix a bug introduced in r38342 that the cflagspat
substitution is messed up by the way CFLAGS and optflags are
modified, which affected FreeBSD and NetBSD/amd64 when
configured to use libexecinfo. This bug resulted in CFLAGS and
CXXFLAGS in RbConfig::CONFIG having warnflags expanded in them,
forcing third-party C/C++ extensions to follow what warnflags
demands, like ANSI/ISO-C90 conformance. ref [Bug #7101]
