[Xen-devel] Xen makefiles wants to write to /..d ?

I confess I'm a rank amateur, but I'm trying to get xen-4.7.0_rc* rammed
into a gentoo package, so that I can try it out and still switch back to
4.6 again as quickly as possible.

I don't have it working yet, but aside from that, gentoo build sandbox
complains about several instances like this:

F: fopen_wr
S: deny
P: /..d
A: /..d
R: /..d
C: /usr/libexec/gcc/x86_64-pc-linux-gnu/4.9.3/cc1 -quiet -nostdinc -I
-MMD /dev/null.d -MF /..d -MQ /dev/null -D __ASSEMBLY__ -D BUILD_ID -D
__OBJECT_LABEL__=include$ -include
- -quiet -dumpbase - -m64 -msoft-float -mtune=generic -march=x86-64
-auxbase-strip /dev/null -g -g -O1 -Wall -Wstrict-prototypes
-Wdeclaration-after-statement -Wno-unused-but-set-variable
-Wno-unused-local-typedefs -Wredundant-decls -Wno-pointer-arith
-Wnested-externs -fno-strict-aliasing -fno-builtin -fno-common
-fno-optimize-sibling-calls -fno-omit-frame-pointer -fno-stack-protector
-fno-exceptions -o -

From what I can *guess* it has something to do with compiling to
/dev/null to generate build dependencies, and this snippet from
Rules.mk: "CFLAGS-y += -MMD -MF $(@D)/.$(@F).d"
Building outside sandbox does create that file in the root of my file
system, but it seems kind of fishy, and the resulting build seems to
have loads of weird problems.

So; am I doing something wrong, or is there a bug in the build system ?
