This commit improves the handling of the "atomic stuff" in the libdrm
package. libdrm can either use the atomic intrinsics (4 byte variant)
when available, or otherwise can use libatomic_ops. Note that the
dependency on atomic operations is not from libdrm itself, but only
from some specific DRM drivers only.
Amongst other things, it fixes the build of the libdrm package on
SPARCv8, therefore fixing:
http://autobuild.buildroot.org/results/74dd29b5ea146c320fde80a87a2fc910de9b7f60/
This commit does a number of changes that are all related to each
other:
- Removes the dependency of the Intel DRM driver on
libatomic_ops. The Intel DRM driver builds perfectly fine without
libatomic_ops, as long as 4-byte variant __sync operations are
available, which is always the case on x86 and x86_84 (which are
the only architectures on which the Intel DRM driver can be
enabled).
- Adds an hidden Config.in boolean option
BR2_PACKAGE_LIBDRM_HAS_ATOMIC that allows DRM driver that need
atomic operation to know whether atomic support is available
(either through intrinsics or through libatomic_ops).
- Adds an hidden BR2_PACKAGE_LIBDRM_ENABLE_ATOMIC Config.in option
that DRM drivers that need atomic operation should select to ensure
that the relevant dependencies are selected. It simply selects
libatomic_ops if 4-byte atomic intrinsics are not available. We
could let each DRM driver do this, but having an intermediate
option avoids a bit of duplication.
- Adds a patch that defines AO_REQUIRE_CAS before including
<atomic_ops.h>. This is needed because libdrm uses the
AO_compare_and_swap_full() which is only provided on all
architectures when AO_REQUIRE_CAS is defined. The exact same fix
was done in the erlang package in commit
4a9df29424.
- Adds the dependency on libatomic_ops when the package is enabled,
and passes the necessary CFLAGS on SPARCv8 to make the thing build
properly. The same CFLAGS are passed in the nginx package and bdwgc
package.

The ARM patch that was added in commit
94841d87fd ("libdrm: fix support for
xserver with Vivante drivers") makes the assumption that ldrex/strex
is available on ARM. While this is true on ARMv6+, it is not true on
ARMv4/ARMv5. Due to this, we had to make follow-up commits like
7bac31ceea
("package/x11r7/xserver_xorg-server: dri needs arm >= v6") and more is
needed in the reverse dependencies to disable DRI usage on
ARMv4/ARMv5.
In fact, it turns out that the CAS code in libdrm is only an
optimization, and it will gracefully fall back to a system call based
lock/unlock mechanism.
So we simply change the patch to only provide the optimized CAS
implementation on ARMv6+. The original reason for this patch was to
fix Vivante drivers, and Vivante GPUs are only used in ARMv6+ cores,
so we should be fine (famous last words).

Thomas reported that the libdrm-radeon dependency on x86 (32- or 64-bit)
dates back to the time where it also depended on libpciaccess.
Now that the libpciacess dependency has been dropped, Thomas managed to
build a libdrm-radeon on something else than an x86 (an ARM for example).
Make libdrm-radeon no longer depend on x86
As a side effect, this fixes some potential "unmet direct dependencies"
from the xdriver_xf86-video-ati package (which was the initial problem
I was trying to solve.)

This patch converts udev to a virtual package. For the moment, there is only
one provider for the udev features: eudev.
Packages meant to provide udev-like features must select the symbol
BR2_PACKAGE_HAS_UDEV.
Packages depending on BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV or
BR2_PACKAGE_UDEV have been converted to use the new symbol.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:
config BR2_PACKAGE_A
depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.
