makefiles/toolchain/gnu.inc.mk: fix compilation
Browse files Browse the repository at this point in the history
The `--param=min-pagesize=0` needed since GCC 12 is still needed with
GCC 13. This time at least the message is more meaningful:

     note: source object is likely at address zero

This is something that is not expected in a userspace app, but with
bare metal MCUs and often flash or memory mapped I/O starting from
address zero, this warning prevents legitimate code from compiling.
