Subject: [PATCH] Introduced support of `MACPORTS_LEGACY_SUPPORT_*`
MacPorts defines `MACPORTS_LEGACY_SUPPORT_ENABLED` with value `1` when
port should link against LegacySupport.
Rust doesn't care about include path, but
`MACPORTS_LEGACY_SUPPORT_LDFLAGS` is a good source path and name for a
library to link.
