Initial single-threaded support of Interix subsystem
* include/private/gc_priv.h [__INTERIX] (_ALL_SOURCE): Define macro.
* include/private/gcconfig.h [__INTERIX] (I386, INTERIX,
mach_type_known): Likewise.
* include/private/gcconfig.h [I386 && INTERIX] (OS_TYPE, DATASTART,
DATAEND, STACKBOTTOM, USE_MMAP, USE_MMAP_ANON): Likewise.
* include/private/gcconfig.h [I386 && INTERIX] (_data_start__,
_bss_end__): Declare extern variable.
