external-toolchain: add support for Linaro 2012.01
Linaro has just released a new pre-built toolchain, available as a tarball, which is a pure toolchain (only the C library is included). This makes this new Linaro 2012.01 toolchain usable in Buildroot, so let's integrate the support for it. In addition to simply adding the new external toolchain at the usual locations, this patch allows need to adapt a few things to support Linaro toolchains. Most toolchains store their libraries in the "lib/" or "usr/lib" directories relative to the toolchain. Buildroot toolchains on the other hand, store the libraries in the "usr/<target-name>/lib" directory. And the Linaro toolchain has choosen to use the "lib/<target-name>" directory. Therefore, this patch adjust: * The logic to search a particular library when that library needs to be copied to the target directory * The logic to deduce the sysroot directory from the libc.a file location in the toolchain: removing "(usr/?)lib(64?)" is no longer sufficient, we need to take into account the "lib/<target-name>/" case. Since the Linaro toolchain generates code for Cortex-A processors only, the selection of this toolchain is limited to Cortex-A8 and Cortex-A9.
