Summary:                    cmake -E tar generated packages with long filenames
can not be processed by PHP's PharData
Description: 
CDash (which uses PharData) can not extract some tar archives as created by
cmake -E tar (e.g. from the CTestCoverageCollectGCOV.cmake module).

The issue seems to be with long filenames.
An equivalent archive created by GNU tar can be extracted by PharData.
GNU tar is also able to extract the cmake created tar.

Steps to Reproduce: 
Create an empty file:
Testing/CoverageInfo/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.c.gcov

Archive it:
cmake -E tar cvfj cmake.tar "--mtime=1970-01-01 0:0:0 UTC" Testing

Trying to extract the archive with PharData produces an exception:
phar error: "/path/to/cmake.tar" is a corrupted tar file (checksum mismatch of
file "133
path=Testing/CoverageInfo/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")

phar error: "/home/ngladitz/topic/phar/input/cmake.tar" is a corrupted tar file
(checksum mismatch of file "133
path=Testing/CoverageInfo/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
