This patch consolidates the connect Linux syscall implementation on
sysdeps/unix/sysv/linux/accept.c. The changes are:
1. Remove connect from auto-generation syscalls.list on the architecture
that uses __NR_connect.
2. Define __NR_connect as default (__ASSUME_CONNECT_SYSCALL) and undef for
architectures that do not support it.

aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.

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.
