[PATCH v2 04/26] lib: md5: prepare for CONFIG_IS_ENABLED changes

[Troy Kisky <troykiskyboundary@gmail.com>]

We need to include <linux/kconfig.h> in order to include
files that use CONFIG_IS_ENABLED. TO prepare for that
don't pet the watchdog when USE_HOSTCC is defined.

Changes in v2:
- delay include of linux/kconfig.h to do from Makefile
- as suggested by Simon
