This is also occurring in latest upstream:

❯ git describe HEAD
v6.2-rc5-13-g2475bf0250de

❯ tuxmake --runtime podman --target-arch sh --toolchain gcc-8 --kconfig microdev_defconfig

`.exit.text' referenced in section `__bug_table' of crypto/algboss.o: defined in discarded section `.exit.text' of crypto/algboss.o
`.exit.text' referenced in section `__bug_table' of drivers/char/hw_random/core.o: defined in discarded section `.exit.text' of drivers/char/hw_random/core.o
make[2]: *** [/home2/tsaeger/linux/linux-upstream/scripts/Makefile.vmlinux:35: vmlinux] Error 1
make[2]: Target '__default' not remade because of errors.
make[1]: *** [/home2/tsaeger/linux/linux-upstream/Makefile:1264: vmlinux] Error 2
make[1]: Target '__all' not remade because of errors.
make: *** [Makefile:242: __sub-make] Error 2
make: Target '__all' not remade because of errors.


FWIW, the above patch resolves this.
How many more architectures need something similar?
