linux-libc-headers: fix headers install in long path name environments
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.
