I think there is another issue in the file: when building for the server or
the host, then it's not patched anymore now. Only when building for the
target, the source would have been patched. Perhaps the patching in the
configuring target was a bad fix?

Here's the patch without having tested anything:

fixes:
* remove patching in the unpacking target (your change)
* also patch before configuring the server or host
* correct prerequisite for target gdb-patched
