-This is an amendment for
-2322dc4 "linux-libc-headers: Fix build failure by using fixed temporary file instead of pipe"
-which moves just the temporary input file from /tmp to build directory. But the
-build directory may not in the same file system with the output file,
-/dev/null, either and thus make it possible to trigger that bug, 67f846b, in
-binutil v2.31.
-
-This patch puts both the input and output files into build directory for good.
