* Added config/arm920t-defconfig-4.3.3
|

* Correct error in arm-defconfig gcc-3.4.6 build. The gcc-3.4.6 configuration
|
||||
does not not take --with-abi
|
||||
* Correct error in gcc-3.4.6/gcc/collect.c. Calls open with O_CREAT but
|
||||
does not specify mode. Newer host compilers can error out on this.
