Subject: [PATCH] makedumpfile: replace hardcode CFLAGS

* Create alias for target such as powerpc as powerpc32
* Remove hardcode CFLAGS
* Add CFLAGS_COMMON to instead of CFLAGS so can flexibly
  customize CFLAGS and not hardcode the CFLAGS as previously
* Forcibly to link dynamic library as the poky build
  system doesn't build static library by default

Upstream-Status: Inappropriate[oe specific]
