+Subject: [PATCH] test_pkgconfig_gen_deps: set
+ PKG_CONFIG_SYSTEM_LIBRARY_PATH=/usr/lib
+
+pkgconf automatically prunes "system library paths" from its output. The
+system library paths depend on the system toolchain. A common value on a
+64-bit system is as follows:
+
+/lib64:/usr/lib64:/usr/local/lib64
+
+So, if -L/usr/lib64 appears in the Libs section, it will be pruned from
+the output of pkg-config --libs.
+
+The pc files generated for this test contain something like this:
+
+libdir=/usr/lib
+Libs: -L${libdir} ...
+
+pkgconf may not consider /usr/lib to be a system library path, so it is
+not pruned as the test expects. To work around this, override the
+compiled-in list of paths via the PKG_CONFIG_SYSTEM_LIBRARY_PATH
+environment variable.
