[jit] Add a libgccjit.pc file for use by pkg-config

Fri Sep 19 01:08:00 GMT 2014
Committed to branch dmalcolm/jit:
gcc/ChangeLog.jit:
* Makefile.in (pkgconfigdir): New.
(installdirs): Add creation of $(DESTDIR)$(pkgconfigdir).
* configure.ac (gcc_version): Expose this value for use via
AC_SUBST, since we need it within the new file libgccjit.pc.in.
* configure: Regenerate.
gcc/jit/ChangeLog.jit:
* Make-lang.in (jit.install-common): Install libgccjit.pc to
"$(DESTDIR)/$(libdir)/pkgconfig".
* config-lang.in (outputs): Define this, adding jit/libgccjit.pc
so that it makes it into AC_CONFIG_FILES and is thus generated from
jit/libgccjit.pc.in at configure time.
* docs/intro/install.rst ("Hello world"): Add discussion about the
use of pkg-config when building against an install in
a non-standard location.
* docs/_build/texinfo/libgccjit.texi: Regenerate.
* libgccjit.pc.in: New.
