[OE-core] [PATCH 0/4 V4] Share gcc work directories

[Robert Yang]

Changes of V4:

* Change the definition of GLIBC_DYNAMIC_LINKER as Richard suggested.

  e.g., the entries in the files that look like:
  #define GLIBC_DYNAMIC_LINKER64 "/lib64/ld-linux-x86-64.so.2"

  become

  #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"

  and we define SYSTEMLIBS_DIR in defaults.h.

  NOTE, the round brackets:
  #define GLIBC_DYNAMIC_LINKER64 (SYSTEMLIBS_DIR "/ld-linux-x86-64.so.2")

  doesn't work in in the following define:

  #define LINUX_DYNAMIC_LINKER \
          CHOOSE_DYNAMIC_LINKER (GLIBC_DYNAMIC_LINKER, UCLIBC_DYNAMIC_LINKER)

  so use:
  #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"

* Compare to V3, reduce two patches which are for gcc-crosssdk.inc and
  gcc-cross-canadian which are not needed any more.

* Fix the conflicts(gcc-4.6.0 -> gcc-4.6, and the ${BRANCH})

* Both tested 4.5.1 and 4.6:
  $ bitbake meta-toolchain core-image-sato
  $ runqemu qemurm

  Also unpack the sdk to /opt and test to make sure the toolchain works well.
