The current taglib-config program does not work when cross-compiling as it only
returns paths to the host, which breaks building programs which link against
taglib.
For example gerbera uses `taglib-config` and it fails with:
```
[..]
-- Found TagLib: -L/usr/lib -ltag
[..]
arm-linux-gnueabihf-g++: ERROR: unsafe header/library path used in cross-compilation: '-L/usr/lib'
```
Before the patch the output of `taglib-config` is:
```
$ ./output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/bin/taglib-config --libs
-L/usr/lib -ltag
```
Add a patch from upstream which fixes taglib-config.
After applying the fix, the pkg-config file is correct:
```
$ ./output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/bin/taglib-config --libs
-L/home/joerg/Development/git/buildroot/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib -ltag
```
