Hello!

Adrian Bunk has had a go at the FTBFS of brltty on ia64 and he finally found a
solution which is passing -static-libgcc to UDEB_LDFLAGS on ia64:

This fixes the FTBFS for me (verified on yttrium.debian.net) and should consequently
fix the FTBFS of debian-installer on ia64, too (once src:linux is fixed as well in
kernel version 5.12).

Thanks,
Adrian
