When Bash attempts to find the current working directory, it uses a C
library call `getcwd` to resolve it. When cross-compiling, the
configuration process cannot determine if the target system's C library
can support an "unfixed" path length. Therefore, Bash will fallback to a
size of `PATH_MAX` for determining the current working directory. When
using OverlayFS (and possible other file systems), this becomes an issue
since file paths can commonly exceed standard `PATH_MAX` length. This
typically results in the following error appearing:
error retrieving current directory: [...]
Common C library `getcwd` calls can default to a higher limit (usually
the system's page size). The current configurable C libraries (as of at
least 2015.08) support a zero (0) size buffer length. Most use the
system's page size; musl, being an exception, which defaults to
`PATH_MAX` (as Bash was doing). Since these C libraries support
allocating buffer space with a zero (0) provided size, the following
configuration change allows Bash to support getting a larger-length'ed
working directory on target's that support it.

Using an intermediate variable to "store" LINUX_VERSION_PROBED is
unnecessary, because they are both recursively-expanded variables, and
the `make kernel-version` code will anyway be used in both places it is
needed; storing in an intermediate variable will not make that a single
expansion of the sub-shell.

Some packages build kernel modules without using the kernel-module infra
(because they use custom build systems); they do not automatically get
the kernel to support modules which is ensured when using the infra.
It must be done manually for all those packages, whenever they are
enabled.
Note: the nvidia-driver case does not need the ifeq-block other packages
use, because it is already enclosed in a more stringent ifeq-block.

This reverts commit 8df95d9 (pkg-kernel-module: die if kernel module
support is disabled).
Now that we force-enable support for modules in the kernel config, we
need not check it.
Besides, the check was broken, because it did not use $$ to dereference
LINUX_DIR, thus leading to systematic build failures when a package
using the kernel-module infra was enabled.

When a package wants to build a kernel module, we should ensure that the
kernel does support modules.
This patch does it automatically for packages using the kernel-module
infrastructure.
Packages that do not use it will have to set it manually (to be done in
a followup patch).

The recent x264 version bump broke the configure step on x86/x86-64 as x264
ends up using gas instead of yasm as assembler. The reason for this is the
recent upstream commit to optionally use nasm instead of yasm if AS= is
passed:
commit b568a256b9bc6c500d7b1ffe4b9c3311ee5ff337
Author: Henrik Gramner <henrik@gramner.com>
Date: Sat May 23 19:44:16 2015 +0200
x86: Experimental nasm support
Enables the use of nasm as an alternative to yasm.
Note that nasm cannot assemble x264 with PIC enabled since it currently doesn't
support [symbol-$$] addressing which is used extensively by x264's PIC code.
This includes all 64-bit Windows and 64-bit OS X builds, even non-shared.
For the above reason nasm is currently intentionally not auto-detected, instead
the assembler must be explicitly specified using "AS=nasm ./configure".
Also drop -O2 from ASFLAGS since it's simply ignored anyway.
But as we pass AS=$(TARGET_AS) it ends up using gas instead. Fix it by
explicitly passing AS=yasm instead.

2015.07 in Buildroot.
Note there's a probability that this particular patch won't make its way

we need to fix U-Boot building in Buildroot anyways.
Hopefully for the next release this patch won't be necessary.

When the rootfs is read-only, keys will be generated in a volatile
location, which is inherently bad as host keys will change on each boot,
rendering them virtually useless.
Add a warning so the user is at least aware of the issue.
Hide the rm output to avoid noisy output, now that we have a proper warning.
Move the starting message after the symlink-block, to avoid messages
collision. Move the umask as well, since /etc/dropbear/ may be world
readable; just the private host keys should be ?00 (and dropbear handles
that by itself).

- in the Config.in file, fix the comment dependency logic (we want

support is missing)
- add hash file.
- do not install to staging, since the package does not install any

- add ibrcommon, ibrdtn and host-pkgconf as mandatory dependencies,
