Indeed, that actually comes from upstream pkg-config, not from Debian
mingw64-tools. The automake macro calls AC_CHECK_TOOL expecting a
$(host)-specific cross-tool (as opposed to AC_CHECK_PROG) just like the
compiler and the linker. So this commit is just matching the expected
pkg-config usage.

Generally speaking, it is not the job of the contrib snippet of the VLC
configure script to guess whether the pkg-config environment is right or
wrong, anymore than that of other build tools. That is the job of the
caller (of the script) or of the SDK. The --with-contrib option is meant to
*add* contribs to the search path.

Besides, comparing $host with $build means nothing (save maybe that you
can run test cases). The caller may well want to override the pkg-config
search path on native compilation. So even if we considered that the VLC
configure script should fix broken pkg-config setups, the test was wrong.
