CVS commit: src/share/mk

["Rin Okuyama" <rin%netbsd.org@localhost>]

Module Name:    src
Committed By:   rin
Date:           Thu Sep 10 02:34:13 UTC 2020

Modified Files:
        src/share/mk: bsd.kmodule.mk

Log Message:
Turn off -mpltseq for kernel modules on powerpc for GCC >= 9.

Otherwise, object files compiled with -mlongcall contain relocation types
referring PLT, which our in-kernel linker cannot handle.

This ends up with failure in kernel module load with
``kobj_reloc: unexpected relocation type 31'' (31 == R_PPC_PLT16_HA here).

See descriptions for -mlongcall in gcc(1) of GCC9 for more details.
