Update gcc9-sh3-lint - instead of disabling optimization for lex.c on

this.

+ descr
+ The in-tree gcc 9/gcc 10 crashes with an internal
+ invalid opcode exception when using any kind of
+ optimization on lex.c in usr.bin/xlint/lint . This
+ was introduced apparently unintendedly in gcc when
+ addressing a different issue. Rather than disabling
+ optimization for lex.c, instead revert the change to
+ gcc. The bug report upstream has been updated to
+ reflect the exact breakage.
