Actually it does.
It's just not pretty.
See http://www.cmcrossroads.com/index2.php?option=com_content&id=7859
(Google it as "GNU Make meets file names with spaces in them", including 
the quotes.)

Note that the more obscure techniques can be reliably used in an LLVM 
context, since LLVM relies on GNU Make anyway.
I do not know whether this will stay so in the future; I guess that's 
for the LLVM team to answer.

The above URL tells me you need to double the backslashes.
I.e. your Makefile should look like this:

all: foo\\ bar
foo\\ bar: foo\\ bar.o

(Disclaimer: I haven't tested this.)

That's actually the strategy that the above-linked text recommends.
(It's also a shame.)
