e53afbbe64 introduce a USE_EXTERNAL_LIBC symbol which gets selected by EXTERNAL_TOOLCHAIN || NATIVE_TOOLCHAIN Currently we always assume uClibc if an external toolchain is used, this breaks for non-uClibc toolchains or even vanilla uClibc ones since they do not share the external librpc semantics as OpenWrt. Solve the problem by defining an abstract "EXTERNAL_LIBC" which packages might or might not depend on.

a3989e3dbd We use different toolchain directories for different ARM archs, so we should set the default arch of gcc to reflect this. 
This enables EABI support for armv4 CPUs.

077d84f543 provide a cleaner way to specify a biarch toolchain build 
Currently, to build a biarch toolchain, we need to explicitly give
options to the binutils and gcc configure commands:

CONFIG_EXTRA_BINUTILS_CONFIG_OPTIONS="--enable-targets=powerpc64-linux-uclibc"
CONFIG_EXTRA_GCC_CONFIG_OPTIONS="--enable-biarch --enable-targets=powerpc64-linux-uclibc"

This change replaces the command line options with an 'extra arch'
configure option:

CONFIG_EXTRA_TARGET_ARCH=y
CONFIG_EXTRA_TARGET_ARCH_NAME="powerpc64"

And a way to invoke this extra arch on the compiler command-line:

CONFIG_EXTRA_TARGET_ARCH_OPTS="-m64"

In this case, this results in an extra compiler:
 'powerpc64-linux-uclibc-gcc', which invokes
 'powerpc-linux-uclibc-gcc -m64'

This is a more standard way of building biarch toolchains, and allows
the packages to not have to care about how to invoke the 64-bit
compiler.
