Tom Tromey 3266f10be2 introduce common.m4
It has bothered me for a while that files in common/ use macros
defined via autoconf checks, but rely on each configure.ac doing the
proper checks independently.

This patch introduces common/common.m4 which consolidates the checks
assumed by code in common.

The rule I propose is that if something is needed or used by common,
it should be checked for by common.m4.  However, if the check is also
needed by gdb or gdbserver, then it should be duplicated there.

Built and regtested on x86-64 Fedora 18 (though this is hardly the
most strenuous case) and using the Fedora 18 mingw cross compilers.  I
also examined the config.in diffs to ensure that symbols did not go
missing.

Mike Frysinger 5b4e221c82 gdb: btrace: fix build errors on older glibc builds
It is possible to have a build of glibc where SYS_perf_event_open is not
defined (because when the glibc was compiled, the syscall did not exist),
but have newer kernel headers installed so that linux/perf_event.h is
available.  In this setup, you get a build failure:

./common/linux-btrace.c: In function 'kernel_supports_btrace':
./common/linux-btrace.c:316:23: error: 'SYS_perf_event_open' undeclared (first use in this function)

Update the ifdef check to also see if the syscall is available.

Pedro Alves 17ef446eed On mainline/development, also link GDBserver with -lmcheck.
This factors --enable-libmcheck related bits from GDB's configure.ac
and makes GDBserver use them too.  Specifically, the 'development'
global is moved to a separate script to it can be sourced by both GDB
and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits
proper are moved to a new m4 file.

I started out by defining 'development' in the m4 file, but in the end
decided against it, as a separate script has the advantage that
changing it in release branches does not require regenerating
configure, unlike today.

I had also started out by making the new GDB_AC_LIBMCHECK itself
handle the yes/no default fallback depending on release/developement,
but since I had split out 'development' to a separate script, and, GDB
needs the python checks anyway (hence we'd need to do the python
checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no'
parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping
GDB_AC_LIBMCHECK isolated from the 'development' global.  IOW, it's
the caller's business to handle it.

Tested on x86_64 Fedora 17.  Built GDB and GDBserver with and without
--enable-libmcheck, and observed --enable-libmcheck overrides the
disablement of -lmcheck caused by python supporting threads, and that
GDBserver links with -lmcheck when expected.  Also observed that
changing the 'development' global, and issuing "make" triggers a
relink, and '-lmcheck' is included or not from the link accordingly.

Pedro Alves bc7dea8de9 Rely on gnulib's unistd.h replacement.
With gnulib's unistd module, we can assume unistd.h is always present, and that
STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO are always defined.

Don't remove unistd.h from GDB's configure.ac, as later tests in the
file use HAVE_UNISTD_H checks.

Mircea Gherzan 257b6bec77 gdbserver: fix the standalone build
When directly invoking gdb/gdbserver/configure && make, the build will
fail because the $(host_alias) is empty and thus create-version.sh does
not get enough parameters.

The output of gdbserver --version without this patch (built like above):

  [...]
  This gdbserver was configured as ""

After applying this patch:

  [...]
  This gdbserver was configured as "x86_64-unknown-linux-gnu"
