Installing ghc-7.10.2 linux binary distro on SuSE

[Levent Erkok]

Thanks Aycan. The LD_PRELOAD solution did indeed work. I didn't know about
that facility before, so I'm pleasantly surprised.

One gotcha though: I had to add the "fake-library" into the runtime as
well; with a command that looked like this:

    ar q libHsrts_thr.a ghcFakeLib.o

where the libHsrts_thr.a comes from the binary distro, and the ghcFakeLib.o
is the object file I got by defining those pthread_setname_np and
pthread_getname_np. (They do nothing but return 0.)

Thanks,

-Levent.
