Series arch: syscalls: unifiy all syscalltbl.sh into scripts/syscalltbl.sh | expand

Commit Message

Masahiro Yamada Jan. 28, 2021, 12:50 a.m. UTC
As of v5.11-rc1, 12 architectures duplicate similar shell scripts in
order to generate syscall table headers. My goal is to unify them into
the single scripts/syscalltbl.sh.

This commit converts m68k to use scripts/syscalltbl.sh.
