* examples/Makefile.am: Fix the installed guile-config invocation to set
PKG_CONFIG_PATH.
* meta/Makefile.am (EXTRA_DIST): Dist the bin_SCRIPTS.
* meta/guile-config (pkg-config): Better error messages if pkg-config
invocation fails.
* meta/uninstalled-env.in (PATH): Now that guile-config and guile-tools
are not generated, make it the srcdir/meta instead of the builddir.
(Guile itself will be picked up from libguile.)
* meta/guile-1.8.pc.in: Include a pkgdatadir, which will map down to
`guile-config info pkgdatadir', used in existing guile.m4 files.
* meta/guile-config: Fix guile-config info varname. Facepalm.
* meta/guile.m4: Make GUILE_SITE_DIR use the sitedir variable instead.
Really it should use pkg-config directly, though.
* configure.in:
* meta/Makefile.am (EXTRA_DIST): Remove guile-config.in bits.
* meta/guile-config: Reimplement to work on top of pkg-config. This lets
guile-config not be substed by configure.
* meta/uninstalled-env.in: Remove the path to guile-config, belatedly.
Set the pkg-config path correctly.
