ldb 2.1.2: test_get_size failure on ppc64el

[Andreas Hasenack]

Hi,

I'm building ldb 2.1.2 on ubuntu groovy 20.10, along with all the
other dependencies for samba 4.12.2, and I'm getting this test error
on ppc64el only:

[ RUN      ] test_get_size
[  ERROR   ] --- 13369 is not within the range 2500-5000
[   LINE   ] --- ../../tests/ldb_kv_ops_test.c:1721: error: Failure!
[  FAILED  ] test_get_size
[==========] 13 test(s) run.
[  PASSED  ] 12 test(s).
[  FAILED  ] 1 test(s), listed below:
[  FAILED  ] test_get_size

That assert use to be

assert_true( size > 2500);

but was changed to

assert_in_range(size, 2500, 5000);

Is that 5000 ceiling limit just a guess, or is this failure indicating
a real bug somewhere? The value 13369 I got on ppc64el seems a bit
excessive. On amd64, size is 2572, so it falls within that range.
