Hi,
This patch (diff-le-config-2) backports more configure changes,
particularly for multilib/multiarch targeting powerpc64le.
Thanks,
Bill
2014-03-19 Bill Schmidt <wschm...@linux.vnet.ibm.com>
Apply mainline r202190, powerpc64le multilibs and multiarch dir
2013-09-03 Alan Modra <amo...@gmail.com>
* config.gcc (powerpc*-*-linux*): Add support for little-endian
multilibs to big-endian target and vice versa.
* config/rs6000/t-linux64: Use := assignment on all vars.
(MULTILIB_EXTRA_OPTS): Remove fPIC.
(MULTILIB_OSDIRNAMES): Specify using mapping from multilib_options.
* config/rs6000/t-linux64le: New file.
* config/rs6000/t-linux64bele: New file.
* config/rs6000/t-linux64lebe: New file.
