This reduces open coding and allows to easily add a knob to
enable it treewide, where chosen packages can still opt-out via
"no-gc-sections".
Note: libnl, mbedtls and opkg only used the CFLAGS part without the
LDFLAGS counterpart. That doesn't help at all if the goal is to produce
smaller binaries. I consider that an accident, and this fixes it.
Note: there are also packages using only the LDFLAGS part. I didn't
touch those, as gc might have been disabled via CFLAGS intentionally.

This patch fixes a recently found problem when a zImage passed to
kexec-tools contains an appended DTB. In that case kexec boot fails because
the decompressor wrongly tries to use the non-existing appended DTB instaed
of the one passed in the register r2.

kdump was removed in 7acd257ae67b4ca94f8c23cb8bda0ee0709b9216
gdb can be used as an alternative.
Remove autoreconf. It's not needed as the configure files are already
generated.
Remove upstreamed patch.

This patch is in a series to allow additional STOP indexes after umount,
so that other block devices may stop cleanly.
kdumpinit is now STOP=90

After commit e82a4d9cfb ("config: regenerate *_shipped sources") the mconf
parser became more strict as a side effect and started to spew a series of
warnings when evaluating our generated kconfig sources:
tmp/.config-package.in:705:warning: ignoring unsupported character '@'
The root cause of these warnings is a wrong use of the @SYMBOL dependency
syntax in various Makefile. Fix the corresponding Makefiles by turning
`@SYM||@SYM2` expressions into the proper `@(SYM||SYM2)` form.

With no warning, it just looks like the box has hung during boot.
We don't want users resetting it without having captured a crashdump.

split kexec-tools into two packages, kexec and kdump.
* kexec to simply execute a new kernel
* kdump is for loading and collecting debris of a crashed kernel with
support for kdump forensics.
In order to properly support booting into a crashkernel, an init script
as well as UCI configuration has been added.
As modifying the kernel cmdline is required for this to work in x86
platforms use an uci-defaults script to modify /boot/grub/grub.cfg.
To test collecting crash information, use the 'c' sysrq-trigger, ie.
echo c > /proc/sysrq-trigger
This should result in the crash kernel being executed and (depending
on the configution) dmesg and/or vmcore getting saved.
To check if the crash kernel was loaded properly, use the 'status'
command of the kdump init script.

- kexec-tools is now distributed with tarballs of .tar.gz and .tar.xz
format; .tar.bz2 are not provided anymore.
- Add CONFIG_KEXEC_LZMA for selecting lzma support.
Patches are updated along to:
- Remove the now unnecessary patch 0004-mips_regdefs.patch.
- Drop 100-reduce_size.patch because the size reduction is marginal.
- Allow zlib and lzma support coexist together. This patch has been
merged into upstream project.
- Fix kexec-tools' configure.ac.
- Fix a few compilation warnings.
Size comparison of stripped binaries of kexec malta target with both
zlib and lzma support enabled.

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information
and/or did not miss license information.
