Fix build problems under Cygwin
This patch allows u-boot to build without error in a cygwin
environment. Cygwin does not define __u64 in it's
include/asm/types.h file. The -idirafter flag in the u-boot
build causes the inclusion of the cygwin types.h file as opposed
to u-bot/include/asm/types.h file which does define __u64.
Subsequently, sha1.c compile fails due to unknown symbol.
