Can't this be configured to something else (eg. /usr/include/foobar/asm ) ?

If I understand OP correctly, the goal is simply to have multiple
compilers installed this seems to work fine for
crossbuild-essential-*, so it would be nice to also have it for
gcc-multilib. Does this means we need a new package:
crossbuild-essential-i386 to get both `gcc -m32 (gcc-i386-linux-gnu)`
and `gcc-aarch64-linux-gnu` installed at the same time ?

Thanks for clarification,
