Problems building gdbserver in binutils 2.46

[Tom Kacvinsky]

Hi,

Using CentOS 70 - which has glibc 2.17 and kernel 3.10.0 - and using the
tool chains

  GCC 12.1.0
  binutils 2.39
libtool 2.47

and then building binutil 2.46 from source without specifying
--disable-gdbserver, I got this build error

CXX    nat/x86-linux.o

In file included from
../../binutils-gdb/gdbserver/../gdb/nat/x86-linux.c:22:

../../binutils-gdb/gdbserver/../gdb/nat/x86-linux.c: In function ‘bool

I know this is an EOL Linux distribution, but for the moment that is
what I need to build our product.  From what research I have done,
PTRACE_GET_THREAD_AREA and PTRACE_TYPE_ARG1 are only available in newer
versions of glibc.

Any ideas how to fix this so one doesn't have to specify
--disable-gdbserver? I am worried that future builds of gdb from the
binutils-gdb repo will no longer build on CentOS 7.

Thanks,

Tom
