klibc: cleanup all version

klibc: cleanup all version

* reuse as much .inc as possible
* use INC_PR
* added klibc-utils.inc with common do_install_append for installing all utils
  added PACKAGES + FILES variables for them (union for all klibc versions)
* added klibc-utils-static.inc with common part of all klibc-utils-static recipes
  and including klibc-utils.inc in the end with prepared variables to install
  static versions
* modprobe was installed in base_bindir for shared and base_sbindir for static, unified
  to base_sbindir
* next task will be to  convert all to new staging (don't know how to install to cross
  with native install).

* 1.5.15 tested with slugos/nslu2le linux-ixp4xx-2.6.27.8+svnr1089-r2
* >= 1.5.15+1.5.16 tested with angstrom/spitz linux-2.6.34-rc6+git%

* all version:
  with newer kernel version where is no include/asm, which is
  replaced with include/asm-generic + ie arch/arm/include/asm/
  we can stage asm -> ../arch/arm/include/asm/ link, or fix klibc
  autotools to use arch inludes correctly

* >= 1.5.15+1.5.16:
  expects newer kernel and also built (staged) after
