[meta][PATCH 05/07] kernel-devsrc: ship tools/include for archscripts host tools

[bruce.ashfield@gmail.com]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Since 7.2, "make scripts prepare" builds arch/x86/tools/vdso2c as part of
the archscripts target. vdso2c is compiled with -I$(srctree)/tools/include
and resolves <linux/types.h> to tools/include/linux/types.h, which pulls
in <stdbool.h>. On target that header was only shipped inside the objtool
block, but objtool is built on x86-64 only (arch/x86/Kconfig: select
HAVE_OBJTOOL if X86_64). A 32-bit x86 kernel-devsrc build therefore lacked
tools/include, fell back to include/uapi/linux/types.h (which does not
define bool), and failed:

  arch/x86/tools/vdso2c.c:74:9: error: unknown type name 'bool'

Copy tools/include unconditionally so the archscripts host tools build
regardless of whether objtool is present.
