The confvar macro is adjusted to not only consider if a variable has a
value or not, but also the value itself. Instead of creating a string of
'y' and 'n' characters, all variable names and values are concatenated
and hashed.

Passing -iremap argument separately causes problems with projects that
use scons and its ParseFlags function. Consider this SConscript
example:

    env = Environment()
    d = env.ParseFlags("-iremap one:two")

ParseFlags will interpret one:two as a file name and the returned dict
d will contain only "-iremap". When the -iremap is passed to the
compiler without an argument, compilation obviously fails.

For external toolchain, we also know the type of C library used, and the
toolchain triplet may not always be reflective of that, therefore make
$(TARGET_DIR_NAME) suffixed with _$(LIBC).

Introduce a new location STAGING_DIR_IMAGE which is intended to be used by
bootloader iamges and similar image-related artifacts.

This directory is guaranteed to be persistent across kernel upgrades which
might involve a removal of KERNEL_BUILD_DIR and is guranteed to be bundled
with the image builder.

Signed-off-by: Felix Fietkau <nbd@nbd.name>

Using a single host package staging dir (and build dir) significantly speeds up
builds when multiple targets are built in succession, especially for large host
packages like NodeJS.

$(STAGING_DIR)/host is kept in addition to $(STAGING_DIR_HOSTPKG) in most
places; it is still used as destination for host files in Build/InstallDev.

This makes it easier to unify versioning of git based package downloads.
PKG_SOURCE_DATE along with an 8-character abbreviation of the git hash
is used as PKG_VERSION, PKG_RELEASE should be used like normal packages.

This is intended to be used for a wide array of package sanity checks.

The first check that is implemented is for the hash of downloaded files.
It checks:
  - Missing hash
  - Use of SHA256 instead of MD5
  - dl/<file> hash not matching hash in makefile
  - deprecated MD5SUM variable

The deprecated MD5SUM variable check is skipped for feeds/ until OpenWrt
is updated as well

Add a new "checksum" make target which generates an sha256sums file over the
image files produced in bin/targets/ and automatically call it during make
world after the package index generation.

The advantage of this new target is that it is guaranteed to run after the
images, the SDK and the ImageBuilder archives have been generated to ensure
that they all end up in the checksum file. Fixes FS#51.

Uses sed to postprocess the OpenSSL digest output into an sha256sum command
compatible format.

This change adds support for specifying a build ID for kernel modules.
This is done by setting PKG_BUILD_ID to a hexadecimal string, which will
then be passed to the kernel linker. In addition, when this flag is set,
the build ID debug symbol (.note.gnu.build-id) will not be stripped from
the kernel module. This symbol is exported in sysfs by the kernel (if
the kernel is compiled with CONFIG_KALLSYMS) and so can be used to
uniquely identify a version of a kernel module in a running kernel. This
is useful for keeping track of different versions of a module when doing
experiments and development.

Modules that specify the build ID will be ~100 bytes larger (depending
on the length of the build ID specified). There is no size difference
for kernel modules that do not set this variable.
