This is an issue that I ran into it while updating sys-kernel/mips-sources. Due to this change in sys-devel/make-4.4* (taken from the NEWS file): > * WARNING: Backward-incompatibility! > Previously only simple (one-letter) options were added to the MAKEFLAGS > variable that was visible while parsing makefiles. Now, all options are > available in MAKEFLAGS. If you want to check MAKEFLAGS for a one-letter > option, expanding "$(firstword -$(MAKEFLAGS))" is a reliable way to return > the set of one-letter options which can be examined via findstring, etc. The kernel can drop into silent build mode if command-line variables are passed in on the command line and those variables contain the letter 's': E.g., here's a snippet of expected cross-compile behavior make-4.3 on a mips-sources build where everything should work right (make --version output trimmed for brevity): > # make --version > GNU Make 4.3 > > # make ARCH=mips CROSS_COMPILE=mips64-unknown-linux-gnu- -j14 vmlinux > HOSTCC scripts/kconfig/conf.o > HOSTLD scripts/kconfig/conf > scripts/kconfig/conf --syncconfig Kconfig > SYSTBL arch/mips/include/generated/asm/syscall_table_32_o32.h > SYSTBL arch/mips/include/generated/asm/syscall_table_64_n32.h > [snip] Note the call to scripts/kconfig/conf ONLY passes --synconfig. This is expected behavior. This snippet shows the problem: > # make --version > GNU Make 4.4.1 > > # make ARCH=mips CROSS_COMPILE=mips64-unknown-linux-gnu- -j14 vmlinux > scripts/kconfig/conf -s --syncconfig Kconfig > kernel/extable.c: In function 'sort_main_extable': > kernel/extable.c:37:59: warning: comparison between two arrays [-Warray-compare] > 37 | if (main_extable_sort_needed && __stop___ex_table > __start___ex_table) { > | ^ > kernel/extable.c:37:59: note: use '&__stop___ex_table[0] > &__start___ex_table[0]' to compare the addresses Note that in this instance, the '-s' flag was passed to scripts/kconfig/conf which enabled silent build mode. This is because of the change in make-4.4 that causes the kernel's preexisting logic for the '-s' flag to be insufficient (the compiler warning is expected output in this case, but it's the *only* output because of the silent mode). It's the "ARCH=mips" that likely is the trigger here. Commit 4bf73588165b upstream will fix this in 6.3, but kernels going back to, possibly, 4.13 will need to be patched. I am not certain yet if this fix will get passed over to -stable and show up in the LTS kernel versions. I've also referenced a bug on GNU Savannah in the Make project that has additional detail and proposes a fix in make itself, given the longevity of some kernel versions.
Thanks. Looks like it's flowing down to stable.

Yup, thanks for tracking!
