It is as the message says. .rodata is an allocated section (SHF_ALLOC) and so
cannot be ELF section compressed. This is explicitly not allowed by the spec
because it would make mapping such a section into memory awkward (there is no
corresponding program header flag, so it would be unclear how the dynamic
linker should map a segment that contains a compressed section, especially
since the segment/section mapping isn't 1-on-1 and can be about partial
sections).
