Practically speaking, MIPS has three useful ABIs: * o32 is for 32-bits CPUs, or 64-bit CPUs running only a 32-bit subset of the instruction set. * n32 is for 64-bits CPUs only. It has 32-bits pointers and long integers. * n64 is for 64-bits CPUs only. It has 64-bits pointers and long integers. See http://www.linux-mips.org/wiki/MIPS_ABI_History and http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64 for more details. So, this commit reworks the Buildroot MIPS support by: * Add separate mips64/mips64el top-level architectures. * Renaming the n32 ABI option to BR2_MIPS_NABI32, for consistency with BR2_MIPS_OABI32. * Renaming the n64 ABI option to BR2_MIPS_NABI64, for consistency with BR2_MIPS_OABI32. * Make the n32 and n64 ABI selections select the BR2_ARCH_IS_64, since those ABIs are valid on 64-bits CPUs only. * Removing the o64 ABI, which is practicaly never used. * Removing the "none" ABI, which really doesn't make sense. * Introduce the mips64 and mips64el architecture names when a 64-bits MIPS ABI is choosen. This will fix build issue like http://autobuild.buildroot.org/results/9b8c5ea86c953a89e85e7b67e9221de41773f652/build-end.log where gmp was confused by the fact of having a 32 bits architecture (detected by the mips- architecture part of the tuple) but 64 bits integer size when compiling. * Adjust the uclibc.mk logic to support the new mips64/mips64el architecture names, and take into account the renaming of the ABI options. This has been build tested by generating Buildroot toolchains and compiling a few packages for MIPS o32, MIPS n32 and MIPS n64. This work is originally based on prior work done by Gustavo Zacarias.
