attempts to flash hundreds of MB when ELF contains .uninit sections with LMA in RAM (e.g., from defmt-rtt)

[Oveln]

When flashing an ELF file that includes an uninitialized RAM section (e.g., .uninit.defmt-rtt.BUFFER from defmt-rtt), wlink incorrectly treats it as a loadable segment with physical address (LMA) in RAM (e.g., 0x20000038)
