FAIL: gcc.target/i386/pr78904-4a.c scan-assembler [ \t]movb[\t ]+%.h, t

when compiled with --target_board='unix{-m32\ -march=cascadelake}'.  With
-mtune=generic:

	movzwl	4(%esp), %edx
	movl	8(%esp), %eax
	movb	%dh, t(%eax)
	ret

With -mtune=cascadelake:

	movzbl	5(%esp), %edx
	movl	8(%esp), %eax
	movb	%dl, t(%eax)
	ret

Add -mtune=generic for --target_board='unix{-m32\ -march=cascadelake}'.

	* gcc.target/i386/pr78904-4a.c: Compile with -mtune=generic.
