There are two environment variables that are baked into our cross-compilation container images at build time, $CONFIGURE_OPTS and $PKG_CONFIG_LIBDIR: the former contain the options necessary to convince configure to perform a cross build rather than a native one, and the latter is necessary so that pkg-config will locate the .pc files for MinGW libraries. Container images that are not intended for cross-compilation will not have either one defined. The problem is that, while an empty $CONFIGURE_OPTS is completely harmless, setting $PKG_CONFIG_LIBDIR to an emtpy value will result in pkg-config not looking in its default search path, thus not finding any library, and subsequently breaking native builds. To work around this issue, only pass $PKG_CONFIG_LIBDIR to sudo when the value is set in the calling environment.
