Let's make a step towards the growing strace userbase all around
the world and translate something to the language of their choice.
This change enables translation of error messages corresponding
to errno codes, making it consistent with error diagnostics of other
i18n-aware tools, e.g.
$ LANG=es_ES strace -qq -a38 -P /missing unlink /missing
unlink("/missing") = -1 ENOENT (No existe el fichero o el directorio)
unlink: no se puede deshacer el enlace '/missing': No existe el fichero o el directorio

When <sys/reg.h> is included after <linux/ptrace.h>, the build fails
on m68k with the following diagnostics:
In file included from /usr/include/linux/ptrace.h:101:0,
from ptrace.h:51,
from sigreturn.c:2:
/usr/include/m68k-linux-gnu/sys/reg.h:26:3: error: expected identifier
before numeric constant
PT_D1 = 0,
^
Apparently, the only architecture where strace needs definitions
provided by <sys/reg.h> is x86_64, other three (m68k, tile, and x86)
are fine with definitions already provided by <linux/ptrace.h>.
Fix the issue by getting rid of <sys/reg.h> and defining necessary
macros in linux/x86_64/arch_regs.h file.
* configure.ac (AC_CHECK_HEADERS): Remove sys/reg.h.
* regs.h: Do not include <sys/reg.h>.
* linux/x86_64/arch_regs.h (R15, R14, R13, R12, RBP, RBX, R11, R10,
R9, R8, RAX, RCX, RDX, RSI, RDI, ORIG_RAX, RIP, CS, EFLAGS, RSP, SS,
