'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

Some temporary files were generated in /tmp, others in the current
directory, and none was "dpdk prefixed".
All these files have a common path prefix now: $TMPDIR/dpdk.
TMPDIR is /tmp by default.
Note: the previous use of mktemp, with a template but without -t,
was generating a file in the current directory.

There are random build errors in test reports [1]. Build error
is not directly related to DPDK but observed during DPDK build.
When I get similar unexpected build errors in my system, found
out that /dev/null is invalid.
It seems ICC overwrites the /dev/null with "icc -o /dev/null" instead
of sending output to /dev/null. This is not always reproducible, so
hard to say what exactly is triggering the error.
I suspect test-report build errors can be because of the same reason,
and it is good to add a protection for this case.
Instead of sending output to /dev/null save it to the tmp folder and
remove it back when done.

There is already a directory buildtools for pmdinfogen used by
the build system. The scripts used in makefiles are moved here.
