Simplify tilegx sysdeps folder

Browse Source 
With tilepro support removal we can now simplify internal tile support by
moving the directory structure to avoid the unnecessary directory levels
in tile/tilegx both on generic and linux folders.

Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with
and without the patch, there is no difference in generated binary with
a dissassemble.

	* stdlib/bug-getcontext.c (do_test): Remove tilepro mention in
	comment.

/* TILE-Gx specifies that "unsigned int" is sign extended in the high
32 bits. But since the userspace API claims to be "unsigned long",
calls into __ioctl() will not be sign extended, but rather pass all
64 bits of the argument. Therefore, when we pass the "request"
value to the kernel, we must explicitly sign-extend it to match the
kernel's internal use of "unsigned int" as the second argument,
which we do by casting to "unsigned int". */
