I was actually digging about that problem. It is indeed present in
version 1.4.0, but is fixed in the current git master. The problem is
actually not directly in QEMU but in seabios, the update to version
184.108.40.206 commit 5c75fb10) fixes the issue. Maybe it is worth
cherry-picking it into stable-1.4 (hence the Cc:). In the meantime
using bios.bin from master with QEMU version 1.4.0 should also fix the
What is strange is the seabios commit fixing the issue:

build: Don't require $(OUT) to be a sub-directory of the main directory.
Remove references to "../" and "out/" from the build so that "make
OUT=/a/b/c/" will work.
