libfslcodec: Don't try to split debug symbols

The debug symbol split now raises an error as bellow:

,----[ Error ]
| Failed to write file: invalid section alignment
| ERROR: debugedit failed with exit code 1 ...
`----

This happens because the binaries from Freescale are stripped, to
avoid it we need to avoid the debug splitting.
