[PATCH 0/6 V3] Share gcc work directories

[Robert Yang <liezhi.yang@windriver.com>]

Changes of V3:

1) Use --with-headers to replace the:

   sed -i 's:^\([ ]*\)glibc_header_dir=\"${with_build_sysroot}/usr/include\": ...

2) Fix the build of gcc-cross-canadian

3) Fix gcc-crosssdk which make the source incompatible during its
   building.

4) Test "bitbake meta-toolchain", and also do run test for the
   pokysdk(unpack the toolchain to /opt, setup the env by sourcing
   environment-setup-armv5te-poky-linux-gnueabi, and build some pkgs
   out of poky, then use command file to check the binary file type.

5) Make sure that no gcc build would make the source incompatible,
   except gcc-cross_csl-arm-2008q1.bb, but I think this is fine, its
   BINV = "4.2.3", not 4.5.1 or 4.6.0.

Thanks for Richard's great help.
