If an external module uses exported symbols from another external
module, Kbuild needs to have full knowledge of all symbols to
avoid spitting out warnings about undefined symbols.
Use PKG_EXTMOD_SUBDIRS to point to the build directory which contains
the Module.symvers.
Pass KERNEL_MAKE_FLAGS to the external module build, to inject
KBUILD_EXTRA_SYMBOLS. KBUILD_EXTRA_SYMBOLS holds a space separated list
of Module.symvers, which list all exported symbols.

Multiple sources are hosted on OpenWrts source server only. The source
URLs to point to the server vary based on different epochs in OpenWrts
history.
Replace all by @OPENWRT which is an "empty" mirror, therefore using the
fallback servers sources.cdn.openwrt.org and sources.openwrt.org.

This fixes a few minor issues (partially cosmetic) in ltq-adsl and
ltq-adsl-fw Makefiles:
- fix PKG_SOURCE_URL and switch to https
- remove non-existant FW_NAME variable
- fix package name for config inclusion
- fix config symbol for debugging
Fixes: 1d0a9d0c04 ("move ltq-adsl")

When ASLR_PIE was activated globally these drivers failed to build
because the user space LDFLAGS leaked into the kernel build process.
This was fixed in upstream Linux kernel commit ce99d0bf312d ("kbuild:
clear LDFLAGS in the top Makefile") which went into Linux 4.17. The
lantiq target is now on Linux 4.19 only and these exceptions are not
needed any more.

The package still leaks some user space linker options into the kernel
space. This breaks the build when ASLR is activated, deactivate it for
now.

Do not leak the user space CFLAGS into the kernel space any more, this
allows us to activate the MIPS16 build.
