[LTP] [RFC 0/3] syscalls: Rearrange sigwait syscall tests

[Viresh Kumar]

Hi Cyril,

As suggested by you I have tried to rearrange stuff here and having some
difficulty in getting rid of the last few build and runtime errors. And
so sending this as RFC.

Problem 1: Build failure.
---------

This fails with the error:
ltp/libs/libltpsigwait/sigwaitinfo01.c:53: undefined reference to `create_sig_proc'

create_sig_proc() is defined in lib/ and I am trying to use it in libs/.
Somehow linking is failing here as there is no local user of the routine
create_sig_proc() within lib/ directory. If I create a dummy user
(https://pastebin.com/LiNukt1n) there, then the build passes.

I don't know how to properly fix this.

Problem 2: Runtime breakage.
---------

If I build it using the earlier hack then at runtime I have started to
get following error while running the tests now, right after the first
test passes:

tst_test.c:362: BROK: Child (14595) killed by signal SIGTERM

I don't really understand why this has started to come up now, while it
didn't happen earlier at all.

This is rebased over the earlier series which is under review
(specifically the following patch,
[PATCH V7 10/19] syscalls/rt_sigtimedwait: Add support for time64 tests).
