Yes, seems that GDB (or some version of) refuses to load any symbols
at all, also not from stabs, if dwarf info (which comes from crt1/i/n.o)
is broken.

And that might well be because of missing relocation which is because
of (as foobar wrote):

And this (IMO still wrong) addition has some history.  Initially from
myself:
http://repo.or.cz/tinycc.git/commitdiff/0d598aca

then reverted:

then re-reverted by seyko, for some reason:
http://repo.or.cz/tinycc.git/commitdiff/92024ab0

But why, as the comment suggests, some versions of GDB work better if
dwarf info is broken remains a mystery to me.  Maybe these won't
load stabs if dwarf is ok.

If it were me I'd still just remove that "&& (s->sh_flags & SHF_ALLOC))".

And maybe set "seencompressed = 1" from the beginning and not load
any dwarf at all ;)

Whatever...
