Simon Marchi de83289ef3 Pass PKG_CONFIG_PATH down from top-level Makefile
[Sending to binutils, gdb-patches and gcc-patches, since it touches the
top-level Makefile/configure]

I have my debuginfod library installed in a non-standard location
(/opt/debuginfod), which requires me to set
PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config.  If I just set it during
configure:

    $ PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config ./configure --with-debuginfod
    $ make

or

    $ ./configure --with-debuginfod PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config
    $ make

Then PKG_CONFIG_PATH is only present (and ignored) during the top-level
configure.  When running make (which runs gdb's and binutils'
configure), PKG_CONFIG_PATH is not set, which results in their configure
script not finding the library:

    checking for libdebuginfod >= 0.179... no
    configure: error: "--with-debuginfod was given, but libdebuginfod is missing or unusable."

Change the top-level configure/Makefile system to capture the value
passed when configuring the top-level and pass it down to
subdirectories (similar to CFLAGS, LDFLAGS, etc).

I don't know much about the top-level build system, so I really don't
know if I did this correctly.  The changes are:

 - Use AC_SUBST(PKG_CONFIG_PATH) in configure.ac, so that
   @PKG_CONFIG_PATH@ gets replaced with the actual PKG_CONFIG_PATH value
   in config files (i.e. Makefile)
 - Add a PKG_CONFIG_PATH Makefile variable in Makefile.tpl, initialized
   to @PKG_CONFIG_PATH@
 - Add PKG_CONFIG_PATH to HOST_EXPORTS in Makefile.tpl, which are the
   variables set when running the sub-configures

I initially added PKG_CONFIG_PATH to flags_to_pass, in Makefile.def, but
I don't think it's needed.  AFAIU, this defines the flags to pass down
when calling "make" in subdirectories.  We only need PKG_CONFIG_PATH to
be passed down during configure.  After that, it's captured in
gdb/config.status, so even if a "make" causes a re-configure later
(because gdb/configure has changed, for example), the PKG_CONFIG_PATH
value will be remembered.

ChangeLog:

	* configure.ac: Add AC_SUBST(PKG_CONFIG_PATH).
	* configure: Re-generate.
	* Makefile.tpl (HOST_EXPORTS): Pass PKG_CONFIG_PATH.
	(PKG_CONFIG_PATH): New.
	* Makefile.in: Re-generate.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
