[PATCH] semihosting: add O_BINARY flag in host_open for NT compatibility

[Evgeny Iakovlev <eiakovlev@linux.microsoft.com>]

Windows open(2) implementations opens files in text mode by default and
needs a Windows-only O_BINARY flag to open files as binary. Qemu already
knows about that flag in osdep.h, so we can just add it to the
host_flags for better compatibility when running qemu on Windows.
