Subject: fix cross compilation

The OH_SET_SIZES macro relies on the usual autoconf sizeof cache variables
during cross compilation, but it never ensure that they are initialized.

pkg-config must be called with $ac_tool_prefix and PKG_PROG_PKG_CONFIG takes
care of that. Setting PKG_CONFIG_PATH breaks the pkg-config-cross-wrapper.
Don't do that.
