PKG_PROG_PKG_CONFIG and that it should be used if the first call

+ * pkg-config.1: Apply patch from Ed Catmur to document

* configure.in, Makefile.am: Only use -Wall and other gcc-only
Defines the PKG_CONFIG variable to the best pkg-config available,
useful if you need pkg-config but don't want to use PKG_CHECK_MODULES.
+.I "PKG_CHECK_EXISTS(MODULES, [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])"

+Check to see whether a particular set of modules exists. Similar
+to PKG_CHECK_MODULES(), but does not set variables or print errors.
+
+Similar to PKG_CHECK_MODULES, make sure that the first instance of
+this or PKG_CHECK_MODULES is called, or make sure to call
+PKG_CHECK_EXISTS manually
