Yes. The kernel ABI never changes in a backward-incompatible fashion.
Unless you try switching your kernel to ARM EABI and don't update
userspace to match -- don't do that :)
Unless you're using C++, you're more likely to have problems with
different versions of libraries, and buggy code which doesn't compile
correctly with the new compiler, than you are with GCC ABI variations
per se. Especially in the kernel<->userspace interface.
