Fix tic6x-uclinux GDBserver build failure

Browse Source 
I can't find a c6x-uclinux c++ compiler, so I use my host g++ to build
tic6x-uclinux GDBserver, and find the following build failures.  They are
not target specific, so I believe they are real errors.  This patch fixes
them.

	* linux-tic6x-low.c (tic6x_fill_gregset): Cast buf.
	(tic6x_store_gregset): Likewise.
	(tic6x_usrregs_info): Move it up.
