during CppunitTest_sw_htmlexport, apparently for another reason that still needs
investigating.
Upstream <https://git.libreoffice.org/core/+/
a58e086ededb8442938e81f971dfae36ef7eb076%5E!> "rework the default make target"
towards libreoffice-7-0 had dropped the unitcheck and slowcheck targets from the
default target.
But after the preceding b27571d688 "Enable LTO
again", that reveals that there appears to still be issues with LTO at least on
i686, which fails with
> ### unexpected exception content! failed

(<https://koji.fedoraproject.org/koji/getfile?taskID=49136895&volume=DEFAULT
&name=build.log&offset=-4000>), so keep LTO disabled there until the issue is
addressed.
Note that for aarch64, armv7hl, and s390x %check is currently no-op, so it is
not obvious from just building the package whether or not they will have issues
with LTO at runtime. But at least for ppc64le and x86_64 the (non--no-op)
%check has been seen to succeed with LTO enabled, including the
CppunitTest_sw_apitests for which LTO had originally been disabled for LO 6.4 in
5d644f1606 "%check fails with lto enabled" (see
<https://koji.fedoraproject.org/koji/taskinfo?taskID=49136767>).
It had reportedly been disabled due to failing CppunitTest_sw_apitests in
LO 6.4. My recent upstream check with --enable-lto on master towards LO 7.1
found CppunitTest_sw_apitests to work fine, and only found one other failing
test in CppunitTest,xmlsecurity_signing, but which is new for LO 7.1 and not yet
present in LO 7.0 (see <https://git.libreoffice.org/core/+/
800eebfa82106c509310ed43bef38a7a4ad4451f%5E!> "Database document apparently
needs to be closed before it is disposed" and <https://git.libreoffice.org/core/
+/2f2246d22e2a8ccbc1dc3e6f5243734a61edf270%5E!> "external/cppunit: Run tests in
deterministic order".
From a successful scratch build of this commit, it looks like
CppunitTest_sw_apitests already works fine in LO 7.0, and that there are no
other issue with LTO in LO 7.0.
(see <https://docs.fedoraproject.org/en-US/flatpak/>). For one, various paths
need to be configured explicitly, as LO's configure would fall back to hardcoded
/usr paths instead of the /app paths needed here. For another, it is unclear to
me why those three __pycache__ files are not generated, but just not asking to
include them should be harmless.
