We use thread_get_name and thread_set_name to get and set the thread
name, so nothing is stored in the thread structure since these functions
are supposed to be called sparingly.
One notable difference with Linux is that the thread name is up to 32
chars, whereas Linux's is 16.
Also added a mach_RPC_CHECK to check for the existing of gnumach RPCs.
We do not want mach_i386.h to get installed into machine/, but into
i386/ or x86_64/ depending where mach_i386.defs was found, i.e.
according to 32/64 bitness.
We already did the same change for Hurd
(https://git.savannah.gnu.org/cgit/hurd/hurd.git/commit/?id=ef5924402864ef049f40a39e73967628583bc1a4)
Due to MiG requiring the subsystem to be defined early in order to know the
size of a port, this was causing a division by zero error during ./configure.
We could have just move subsystem to the top of the snippet, however it is
simpler to just remove the check given that we have no plans to use some other
MiG anyway.
HAVE_MIG_RETCODE is removed completely since this will be a no-op either
way (compiling against old Hurd headers will work the same, new Hurd
headers will result in the same stubs since retcode is a no-op).

8b8c768e3c ("Force use of -ffreestanding when checking for gnumach
headers") was passing -ffreestanding to CFLAGS only, but headers checks are
performed with the preprocessor, so we rather need to pass it to CPPFLAGS.
Without this ./configure assumes that we are in a fully hosted
environment, which might not be the case. After this patch, we can rely on
the freestanding header files provided by GCC such as stdint.h.

This patch replaced obsolete AC_TRY_COMPILE to AC_COMPILE_IFELSE or
AC_PREPROC_IFELSE.
It has been confirmed that GNU 'autoconf' 2.69 suppressed obsolete
warnings, updated the following files:
- configure
- sysdeps/mach/configure
- sysdeps/mach/hurd/configure
- sysdeps/s390/configure
- sysdeps/unix/sysv/linux/configure
and didn't change the following files:
- sysdeps/ieee754/ldbl-opt/configure
- sysdeps/unix/sysv/linux/powerpc/configure

Autoconf has been deprecating configure.in for quite a long time.
Rename all our configure.in and preconfigure.in files to .ac.
