In 2.6.23-rc1, i386 fiddled its string support such that UML started getting undefined references from modules. The UML asm/string.h was including the i386 string.h, which defined __HAVE_ARCH_STR*, but the corresponding implementations weren't being pulled in. This is fixed by adding arch/i386/lib/string.h to the list of host architecture files to be pulled in to UML. A complication is that the libc exports file assumed that the generic strlen and strstr weren't in use (i.e. __HAVE_ARCH_STR is defined), then they aren't exported. This is untrue for strlen, which is exported in either case, so this logic is not needed.
