Jo-Philipp Wich b84a1c56f3 build: do not alter global default package selection from profiles
This partly reverts ca32373c95 which lets
profiles that suppress packages to alter the package selection for all
devices of the target when building with CONFIG_TARGET_PER_DEVICE_ROOTFS.

In particular, this caused the brcm47xx Edimax PS-1208MFG profile to
disable mtd, dropbear, firewall and other essential packages for all
brcm47xx/generic builds.

To solve this problem, prevent profiles from mangling the global
DEFAULT_PACKAGES selection and restrict the supression of negated
packages to the local PACKAGE variable list only.

include/feeds.mk: always add available feeds to PACKAGE_SUBDIRS
Setting CONFIG_FEED_... symbols combined two different effects: Disabling
a feed in the generated opkg distfeeds.conf, and omitting the feed from
PACKAGE_SUBDIRS.

It does not make sense to omit built feeds from PACKAGE_SUBDIRS, as it will
only lead to packages that can be enabled in .config (and that will
consequently be built) not to be found during rootfs creation, breaking
the build. All feeds that packages are emitted to should simply always be
added to PACKAGE_SUBDIRS instead; the CONFIG_FEED_... only configure the
generated distfeeds.conf like this.

Andy Boyett 25eb240f63 build: add busybox support to `time` prereq-check
Busybox time supports the GNU time '-f' syntax used by the build time
logging implemented in ff6e62b288, however the prerequisite check added
only works with GNU time installed as `time` or `gtime`.

As busybox is a multicall binary, the name of the symlink setup by
SetupHostCommand also must be changed from `gtime` to `time` to fix the
value of argv[0]. This causes a number of shells (including bash) to use
their builtin impelementation of time, so the sole invocation has been
changed to use `env time` to use the value found on the $PATH.

Hannu Nyman b6c134f254 include/image-commands.mk: shorter version in Netgear factory header
Shorten the version string in Netgear factory image header in order
to enable u-boot TFTP recovery flash mode to work again.

Strip 'r7210-14cb05909a' into 'r7210' in the Netgear image header
by removing the hash (anything after "-").

background:
Some Netgear routers have recently been unable to flash Openwrt
factory image with the TFTP recovery flash mode provided by Netgear
u-boot. That is due to over-long Openwrt version string overflowing
into the router type string in u-boot code. Modern git versions
produce 10-digit short hashes for the Openwrt main repo, and that
causes the version string to be too long in the image header,
breaking the image ID verification by the TFTP flash routine.

(Other option could be to force a shorter hash in scripts/getver.sh,
but as the problem only concerns Netgear routers, let's patch just
them.)

More detailed explanations in FS#1583

Jo-Philipp Wich ff8bde5296 build: prevent spurious package rebuilds under CONFIG_AUTOREMOVE
When CONFIG_AUTOREMOVE is enabled, the build system touches an additional
".autoremove" stamp file in the cleaned build directory.

Since the autoremove stamp file is touched after the compile process
completed, it ends up being the most recent file of the package build
directory, causing the timestamp.pl check of depends.mk to erroneously
declare the ".built" and ".prepared" stamp files as stale, triggering
a forced clean-build submake process.

Fix the problem by using the ".built" stamp file as modification time
reference when touching the ".autoremove" stamp file.
