This build failure is raised because pkg-config values are overriden by
AC_LIB_LINKFLAGS which can pull libraries from the host. So, don't
unconditionally call AC_LIB_LINKFLAGS when cross-compiling. It should be
noted that AC_LIB_LINKFLAGS is used as a fallback of case pkg-config
since commit c92eb3c1.
