#64862: owncloud-client: "failed to parse file" during `port selfupdate` on Linux

 I ran `sudo port selfupdate` on Raspberry Pi OS and I get the following
 error:

 {{{
 Failed to parse file www/owncloud-client/Portfile: can't read "build_id":
 no such variable
 }}}

 I think it's due to the following:

 {{{
 configure.args-append
 -DCMAKE_INSTALL_NAME_DIR=${applications_dir}/owncloud.app/Contents/MacOS \
 -DXCODEFLAGS="-IDECustomDerivedDataLocation=${workpath}/DerivedData" \
                         -DMIRALL_VERSION_BUILD=${build_id}
 }}}

 `build_id` is defined in the `platform darwin` block, but is being
 referenced outside of it.
