[PATCHv6 4/9] gdb/x86: move have_ptrace_getregset global into gdb/nat directory

[Andrew Burgess]

Just like the previous commit, this commit moves have_ptrace_getregset
into the nat/ directory.  This global is currently declared and
defined in both GDB and gdbserver, but this can be merged and shared.

There should be no user visible changes after this commit.
