This patch introduces HOST_CPPFLAGS to be used for all objects being compiled with HOSTCC rather then the target compiler. Since glibc is not linked into the EC, no glibc include files should be included in the EC code base. Hence, create local definitions for clock_t and wchar_t that match what the glibc include would have done, and remove some unneeded includes. Due to very eager optimization, we have to give gcc a little notch to not kick out memset.
