John Crispin ff337b8a17 kernel-build: fix STRIP_KERNEL_EXPORTS for recent kernels
Recent kernels started to mark exported symbols as global.
Adapt expressions in kernel-build.mk to also match global symbols
when grep'ing through nm output.

John Crispin f7c3ef012e 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.

Felix Fietkau 7061632fcb 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).
