Meanwhile, Uri mentioned problems with the ABI checks and I've looked into
that on FreeBSD. There are some issues with the current abi_gen.sh script
and, seems, the way how libs are build on FreeBSD(or in the port).

FreeBSD11.* comes with gdb version 6, through the ports version 8 can be
installed. Both versions give smth like:

(gdb) p smbc_fgetxattr
$1 = {int (int, const char *, const void *, size_t)} 0xba60 <smbc_fgetxattr>

which is far from the expected:

int (int, const char *, const void *, size_t)

I wonder what version of gdb do you use for ABI checks? Luckily, we can get
almost the same output with:

(gdb) whatis smbc_fgetxattr
type = int (int, const char *, const void *, size_t)

which is almost what we need and what is easy to fix with some sed magic.
It doesn't help that, it seems, `sort` results do vary on FreeBSD and
Linux(or sorted differently in the .sigs by Python).

Well, I hope to nail that part soon. Would it be possible to use `whatis`
instead of `p` on Linux also?
