[OE-core] [PATCH 15/18] icu: fix buildpaths QA issue

[Hongxu Jia]

- Define new variable U_CC and U_CXX which do not have build path.
  The output of icuinfo will not have build path in it:
  ...
  root at qemux86-64:~# icuinfo
   <icuSystemParams type="icu4c">
      [snip]
      <param name="build.cc">x86_64-poky-linux-gcc -m64 -march=core2 -mtune=core2 -msse3 -mfpmath=sse
      <param name="build.cxx">x86_64-poky-linux-g++ -m64 -march=core2 -mtune=core2 -msse3 -mfpmath=sse
      [snip]
   </icuSystemParams>
  ...

- Remove build paths in pkgdata.inc, Makefile.inc and
  icu-config.
