[LTP] [PATCH v2 2/4] utils/ffsb: Add missing fhstat() signature + includes

[Petr Vorel]

Need for build with -Werror-implicit-function-declaration

Signed-off-by: Petr Vorel <pvorel@suse.cz>

To be hones I'd rather delete this The Flexible Filesystem Benchmark
(FFSB) (in utils/ffsb-6.0-rc2). Does anyone uses it?
If kept, I'd prefer to have it as a separate project in [1]

I probably have asked before and there is a paper from 2012 suggesting
that someone used it 7 years ago [2][3]. There is also a fork, with just a
few patches, no development now [4].

[LTP] [PATCH v2 3/4] build.sh: Respect user defined CFLAGS and LDFLAGS

[Petr Vorel]

Therefore it was needed to export them and not pass as a parameter.

It will be used for travis settings in next commit, but also can be
handy for using build.sh in local development.

[Petr Vorel]

and add it to Travis CI builds.

Previously it was passed only to Android build. Generally Werror flags
should be on for development but disabled for releases and production.
We don't have any configure flag stating development build, so using it
only in Travis CI should be sufficient (although we lost lost this check
for Android as we don't test it in our Travis CI setup).

It's a dependency because the ext4-new-features tests use it.

But these tests already check for ffsb so we may as well remove it from
LTP and either maintain it in a separate repo or point out our users to
the fork.

OK, I overlooked it's really installed. In that case I'd postpone the solution
(hosting at separate project looks cleaner to me, but then we'd need to setup
git subproject) and merge this unchanged.
