When compiling drivers on Windows, instances have been seen where a
temporary directory fails to get cleaned up due to
ERROR_SHARING_VIOLATION (32).
Code inspection did not reveal problems with the DPDK code and scripts,
and this issue was only seen on Windows.
The proposed fix adds a mitigation for this problem, and also sets a flag
to ignore cleanup errors.
For completeness, the error message is included below.
