Subject: gdbserver: fix the standalone build
X-Git-Tag: sid-snapshot-20130701~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=257b6bec774c0b9ec2c52494fc4898f472fcdbb8;p=external%2Fbinutils.git

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"

2013-06-28  Mircea Gherzan  <mircea.gherzan@intel.com>

gdbserver:

	* configure.ac (version_host, version_target): Set and AC_SUBST
	them.
	* configure: Rebuild.
	* Makefile.in (version_host, version_target): Get from
	configure.
	(version.c): Use $(version_host) and $(version_target).
