[OE-core] [PATCH] bitbake.conf: add definition for BUILDSDK_CXXFLAGS

[Chang Rebecca Swee Fun]

${BUILDSDK_CXXFLAGS} was introduced since
commit 55c83cb239df5faf5e2143fffca47f2f16931cb3
cross.bbclass: override TARGET_* flags

bitbake.conf has definitions for both ${BUILDSDK_CPPFLAGS} and
${BUILDSDK_CFLAGS} but there is none for ${BUILDSDK_CXXFLAGS}.
This was a regression as in the past, CXXFLAGS is the same as
CFLAGS in SDK environment.

Adding definition for ${BUILDSDK_CXXFLAGS} will resolve CXXFLAGS
being set wrongly in SDK environment.
