Instead of explicitly passing -m32 and -m64 to the CXX invocation, define CXX_32 and CXX_64 as "CXX -m32" and "CXX -m64", respectively. This allows easily using a cross GCC toolchain instead of GCC's multilib support, for example by defining CXX_32=i686-linux-gnu-gcc, and CXX_64=x86_64-linux-gnu-gcc. See <https://lists.debian.org/msgid-search/[email protected]> and related messages for some more context on why multilib (-m32 and -m64) might get removed from Debian in the future, in favour of cross compilers.
