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
