For openembedded cross-builds CXX can contain something like:
arm-oe-linux-gnueabi-g++ -march=armv5te -marm -mthumb-interwork --sysroot=/home/jenkins/oe/shr-core-branches/shr-core/tmp-eglibc/sysroots/qemuarm
This ends up in
configure:5582: error: No C++ compiler found. Please install a C++ compiler.
Anyway if [1] is still valid, the combination of AC_PROG_CC and AC_PROG_CXX should thow an error message.
