external toolchain: fix libraries copy and add ARM ABI check
Instead of hardcoding the C library versions, just copy the version available in $SYSROOT_DIR/lib. Add a check on the ARM ABI configured in Buildroot with regard to the ABI of the external toolchain provided. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
