Hi Guix!
Since the GCC update, dovecot doesn't build on aarch64 because the
test_backtrace() tests fail :-/. What happens is the backtrace()
function works but only contains addresses and no real symbol names,
which the tests expect.
I was going to propose disabling them, but doing some searching I found
that debian fixed this by using the -rdynamic linker flag [0], and
indeed, looking at GCC's documentation, they suggest using this flag for
symbols to work [1].
I'm not sure why it works OK on other platforms, this flag might be on
by default there.
OK to push?
