The iozone code uses the pthread_setaffinity_np() function, but with
uClibc this function is only available when the NPTL thread
implementation is used. Some architectures, such as AVR32 and ARC do
not support the NPTL thread implementation, and therefore lack the
pthread_setaffinity_np() function.
This commit adds a patch that provides an empty implementation of
pthread_setaffinity_np() when we're using uClibc, but not with the
NPTL thread implementation. The reasoning is that there is a very high
chance that the few architectures that do not implement NPTL are
non-SMP architectures, and therefore setting the affinity is not very
useful.
In addition to this, this commit:
* Renames the existing patch to use a sequence number, in order to
guarantee a proper ordering when applying patches.
* Removes the Kconfig dependency on !uClibc 0.9.31, which was
introduced to prevent AVR32 from failing due to the
pthread_setaffinity_np(). This conditional is no longer necessary
due to the new patch, and the conditional was anyway not completely
working since it was not taking into account the case of external
toolchains.

uClibc 0.9.31.x does not include the pthread_setaffinity_np GNU extension.
Fixes build failures such as the following.

Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.
Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

Fixup iozone's build system to make it somewhat more flexible.
First make our own linux targets for non-AIO toolchains (uClibc) and
non-threading.
And second, just ditch forced largefile support and expect it from
CFLAGS.
Otherwise using the generic target caused issues like:

...which is fixed by this.
