[toolchain] 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.
