Lintian tag information: autotools-pkg-config-macro-not-cross-compilation-safe (type: warning)

Description (from lintian-explain-tags)

The package appears to use AC_PATH_PROG to discover the location of
pkg-config(1). This macro fails to select the correct version to support
cross-compilation.

A better way would be to use the PKG_PROG_PKG_CONFIG macro from pkg.m4 and
then using the $PKG_CONFIG shell variable.

Please refer to Bug#884798 for details.
