Ah and by the way, here's how I tested it:
`compat` format - until 2.32/2.31:
```
root@thinkpad:/home/cf/src/mesos/build# ldconfig -c compat
root@thinkpad:/home/cf/src/mesos/build# ./bin/mesos-tests.sh
--gtest_filter=*Ld* 2>&1 | tail -n13
[----------] 3 tests from Ldd
[ RUN ] Ldd.BinSh
[ OK ] Ldd.BinSh (2 ms)
[ RUN ] Ldd.EmptyCache
[ OK ] Ldd.EmptyCache (0 ms)
[ RUN ] Ldd.MissingFile
[ OK ] Ldd.MissingFile (1 ms)
[----------] 3 tests from Ldd (3 ms total)
[----------] Global test environment tear-down
[==========] 4 tests from 2 test cases ran. (548 ms total)
[ PASSED ] 4 tests.
```
`new` format - supported by this change:
```
root@thinkpad:/home/cf/src/mesos/build# ldconfig -c new
root@thinkpad:/home/cf/src/mesos/build# ./bin/mesos-tests.sh
--gtest_filter=*Ld* 2>&1 | tail -n13
[----------] 3 tests from Ldd
[ RUN ] Ldd.BinSh
[ OK ] Ldd.BinSh (3 ms)
[ RUN ] Ldd.EmptyCache
[ OK ] Ldd.EmptyCache (0 ms)
[ RUN ] Ldd.MissingFile
[ OK ] Ldd.MissingFile (1 ms)
[----------] 3 tests from Ldd (4 ms total)
[----------] Global test environment tear-down
[==========] 4 tests from 2 test cases ran. (550 ms total)
[ PASSED ] 4 tests.
```
`old` format - never supported - as a sanity check:
```
root@thinkpad:/home/cf/src/mesos/build# ldconfig -c old
root@thinkpad:/home/cf/src/mesos/build# ./bin/mesos-tests.sh
--gtest_filter=*Ld* 2>&1 | tail -n13
cache: Invalid format
[ FAILED ] Ldd.MissingFile (0 ms)
[----------] 3 tests from Ldd (1 ms total)
[----------] Global test environment tear-down
[==========] 4 tests from 2 test cases ran. (7 ms total)
[ PASSED ] 1 test.
[ FAILED ] 3 tests, listed below:
[ FAILED ] LdcacheTest.Parse
[ FAILED ] Ldd.BinSh
[ FAILED ] Ldd.MissingFile
3 FAILED TESTS
```
