Subject: [PATCH] fix taglib-config file for cross compiling (#906)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current taglib-config program does not work for cross-compiling as it only
returns the paths to the host, which breaks building programs which uses
`taglib-config` to link against taglib.

Fix this by passing sysroot to the `prefix` and `exec_prefix` fields.

Backported from: 7470f92a67375d00e53b3785a88fa7b26ad6f1da
