main/gcc: fix patch for TARGET_CAN_SPLIT_STACK
It looks like GCC's OPTION_GLIBC_P
is not intended to be used in a pre-processor context. As such, we have to resort to DEFAULT_LIBC in a pre-processor context (at least I don't know any better macro we can check for). This should remove the need for the gospec.c
hotfix.
Let's see if this passes on the CI 🫣
