Rollback ZDS linker to 5.2.0. Version 5.3.0 appears to be broken.

Or at least, something weird is going on with segments definitions.

We have, for instance:
__low_bss                           00D00000 (User Defined)
when it's clearly not defined like this (that's where the RAM starts)

It might be related to 5.3.0's "CR 13377: When padding bytes with 0xFF,
omit padding address ranges that aren't included in the Linker >
Address Spaces listing"
