Move tilegx, tilepro, and linux-generic from ports to libc.
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 c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.
