build system: have tar use $SOURCE_DATE_EPOCH for --mtime
...
The --mtime argument to 'tar' sets the modification time for all files within
the archive, which determines the timestamp files will get when they are
extracted. In this case, rootfs and other tarballs will get mtimes which
correspond to the last commit timestamp of the build system, as reported by
git/subversion.
This is a step towards reproducible image builds.

include: fix kernel download failure with git & local trees
...
When using the options EXTERNAL_KERNEL_TREE or KERNEL_GIT_CLONE_URI,
the command "make downloads" fails as it tries to download the kernel
tarball despite the option. This doesn't happen during a regular build
as in that case, the dependency is conditionned through the LINUX_SITE
variable, which is not set in these cases.
Below is a snapshot of the error for an target using a 3.14 kernel:
make[3]: *** No rule to make target `.../dl/linux-3.14.tar.xz',
needed by `download'. Stop.

build: speed up kernel symbol export stripping
...
GNU grep has a high per-expression setup overhead when compiling regular
expressions. Use -F to force it to interpret the input as fixed strings,
which is much faster (fraction of a second instead of multiple minutes).
