No, only the other way around. It's "multi-arch" to the extent that a linux 64-bit gdbserver (built with target = x86-64) can debug a 32-bit app. It used to only be, only 64x64 or 32x32 was possible; with multi-arch, 64x32 was made possible.

I ask because linux-x86-low.c is full of ifdefs on the architecture.
It looks like most of the 64-bit code won't be compiled if the
build machine is 32-bit.

Correct.

Thanks for confirming.
