Jörg Krause 9eca4b9f84 package/swupdate: fix build issue with some toolchains
Add patch from upstream to fix build issue with some toolchains.

For some toolchains used in Buildroot (x86_64 and mips64) partial linking using
'ld' directly doesn't work well, as the 'ld' default emulation may not
necessarily be the correct one. Note, that the default emulation depends upon
how the linker was configured at build time. The leads to different kind of
build errors, like:

  * /usr/bin/i686-pc-linux-gnu-ld: Relocatable linking with relocations from
    format elf64-x86-64 (core/swupdate.o) to format elf32-i386 (core/built-in.o)
    is not supported.

  * /usr/bin/mips-linux-gnu-ld: handlers/raw_handler.o: endianness incompatible
    with that of the selected emulation

  * /usr/bin/mips64el-linux-ld: core/swupdate.o: ABI is incompatible with that
    of the selected

Linking with gcc will pass all the appropriate linker flags to the linker.
'-nostdlib' has to be added to ldflags-y to link properly without pulling in GCC
libs during partial linking. Note, for Kbuild ldflags-y is prefered over the
deprecated EXTRA_LDFLAGS.

Build config for x86_64:
  BR2_x86_64=y
  BR2_x86_corei7=y
  BR2_TOOLCHAIN_EXTERNAL=y
  BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_X86_201209=y

Runtime test:
  $ output/build/swupdate-2015.07/swupdate -v
  Swupdate v2015.07.0

  Registered handlers:
  	rawfile
	raw

Note, that a previous patch [1] had to be reverted [2] because ld does not take
gcc's constructor functions into account and so none of the handlers have been
registered at runtime.
