There would be an "Argument list too long" error when the TMPDIR is in a
deep dir, for example, when "len(readlink -f TMPDIR) >= 350 (our
supported value is 410)". Use "$(foreach ,,$(shell echo))" to fix it.
There was already a patch which tried to fix this issue, so squash the
current change into the previous one as Bruce suggested.

The autobuilders and their long paths are still triggering errors during
the headers installation. Reinstate the previous patch for this,
after updating for 3.10.

If a build is started in a deep directory structure, or in a path with
long directory names the installation of linux-libc-headers will fail
with:
| make[2]: execvp: /bin/sh: Argument list too long
| make[2]: ***
>From within the kernel Makefiles themselves.
The solution is to patch the kernel build rules with the following
change:
[
scripts/Makefile.headersinst: install headers from scratch file
If headers_install is executed from a deep/long directory structure, the
shell's maximum argument length can be execeeded, which breaks the operation
with:
| make[2]: execvp: /bin/sh: Argument list too long
| make[2]: ***
By dumping the input files to a scratch file and using xargs to read the
input list from the scratch file, we can avoid blowing out the maximum
argument size and install headers in a long path name environment.
]
Until this change, or a similar one, is merged into the mainline kernel, this
change should be applied to any 3.7 or greater libc-headers build.
