build error:
== Build drivers/net/tap
mktemp: cannot create temp file /tmp/dpdk.auto-config-h.sh.XXX.c:
Invalid argument
.../buildtools/auto-config-h.sh: line 86: : No such file or directory
.../drivers/net/tap/Makefile:55: recipe for target
   'tap_autoconf.h.new' failed

Above error observed on Wind River Linux 8.0

`mktemp` command in that system has a restrictions to have X in
the template at the end and at least six of them.

Complied to mktemp requirements and add -xc flag to compiler to say
`temp` file is a C file

Fixes: ff37ca5d3773 ("devtools: use a common prefix for temporary files")

It looks OK for this script.

Should we do the same kind of change for devtools/check-includes.sh?
and devtools/cocci.sh?

Not sure, this script is part of buildtool and required for build, so needs to
be compatible for various systems. Above are devtools and can use new mktemp.

You mean nobody will use Wind River Linux 8.0 for developing?
You are probably right :)
