The decode-tm6000 utility cannot build without the libv4l2util. If
this library is not available, the build breaks with:
decode_tm6000.o: In function `read_stream':
decode_tm6000.c:(.text+0x220): undefined reference to `v4l2_rcvbuf'
decode_tm6000.o: In function `main':
decode_tm6000.c:(.text+0x37c): undefined reference to `v4l2_open'
decode_tm6000.c:(.text+0x3cc): undefined reference to `v4l2_gettryset_fmt_cap'
decode_tm6000.c:(.text+0x424): undefined reference to `v4l2_getset_freq'
decode_tm6000.c:(.text+0x47c): undefined reference to `v4l2_mmap_bufs'
decode_tm6000.c:(.text+0x4a0): undefined reference to `v4l2_start_streaming'
See
http://autobuild.buildroot.org/results/207ed74d5e816309ef0dc82ecc8112b51788fdf6/build-end.log
We fix this by adding util/libv4l2util to the list of directories to
build when decode-tm6000 is enabled. The only other user of
libv4l2util is another utility called qv4l2, for which Buildroot has
no Config.in option, so we only handle the case of decode-tm6000 at
the moment.

In libv4l.mk, if there are multiple elements in $(LIBV4L_DIRS_y), they
are built in order, one after the other. However, our loop construct
doesn't take into account the fact that we should error out if one of
the steps failed.
A good illustration is having BR2_PACKAGE_LIBV4L_DECODE_TM6000 and
BR2_PACKAGE_LIBV4L_V4L2_CTL enabled. The build of decode-tm6000 will
fail, but the build will happily continue without stopping in libv4l.

Now that the lfs handling issues have been worked around, we can
pass TARGET_CONFIGURE_OPTS on the make command line to ensure
TARGET_CFLAGS are used.

Fixes http://autobuild.buildroot.net/results/4602f7cf4407a2969a04267bbc5d276b076a7c91
The preload libraries needs to wrap both the lfs and !lfs variants, so
ensure the lfs versions are not transparently used (as they are when
_LARGEFILE_SOURCE / _FILE_OFFSET_BITS=64 are defined).
This used to work by accident before, as our custom CFLAGS (containing those
defines) wasn't used.

Also remove the redundant $(call ...).
This is a purely mechanical change, performed with
find package linux toolchain boot -name \*.mk | \
xargs sed -i -e 's/$(eval $(call GENTARGETS))/$(eval $(generic-package))/' \
-e 's/$(eval $(call AUTOTARGETS))/$(eval $(autotools-package))/' \
-e 's/$(eval $(call CMAKETARGETS))/$(eval $(cmake-package))/'

Thanks to the pkgparentdir and pkgname functions, we can rewrite the
GENTARGETS macro in a way that avoids the need for each package to
repeat its name and the directory in which it is present.

These have extra deps though (C++ for some, argp.h for others which is not
available on uClibc).
