This patch makes tilegx32 install libraries in lib32 directories,
matching what GCC expects and avoiding conflict with 64-bit libraries
installed in lib directories.
Tested (compilation only) for tilegx (32-bit and 64-bit, BE and LE,
GCC 5).
* sysdeps/unix/sysv/linux/tile/tilegx/configure.ac: Use
LIBC_SLIBDIR_RTLDDIR for tilegx32.
* sysdeps/unix/sysv/linux/tile/tilegx/configure: Regenerated.
I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure. Beyond the README
update, the move was just
git mv ports/sysdeps/tile sysdeps/tile
git mv ports/sysdeps/unix/sysv/linux/tile \
sysdeps/unix/sysv/linux/tile
git mv ports/sysdeps/unix/sysv/linux/generic \
sysdeps/unix/sysv/linux/generic
I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d7 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.
