I'm not expert (seriously - this isn't just modesty :) but it looks
like that uml is undefining strstr but not __HAVE_ARCH_STRSTR so that
when it's compiled on an arch that defines __HAVE_ARCH_STRSTR because
it has strstr it's only half undefined. If I'm right it appears to
be a bug in the part of uml.

Check linux/arch/um/os-Linux/user_syms.c. It includes string.h
which includes asm/string.h which includes asm/arch/string.h which
points to asm-i386/string.h which would define the above.

I've CCed the happy-fun folks at UML to be sure because my feeling that
I'm talking sheer bollocks is about as strong as my feeling that I am
not. :)

    Red herrings strewn hither and yon.
