libaio-devel requirement breaks built on Debian Sid

[spadegit]

Dear ZoL Developers,

since the last commit (55972a6) I can't build ZoL on my Debian Sid box anymore.

I don't really want to bother You, since this is just my local toy box, but wanted to bring this to your attention.

I installed the Debian package libaio-dev but no success:

dpkg -l | grep libaio

ii  libaio-dev:amd64                              0.3.111-1                               amd64        Linux kernel AIO access library - development files
ii  libaio1:amd64                                 0.3.111-1                               amd64        Linux kernel AIO access library - shared library

Since this might just be an isolated error resulting from some new/exotic constellation, please feel free to close this bug by your considerations.

In any way: thank You all for your great work, I am using ZoL for years now and enjoy using the fruits of your labor :).

Describe the problem you're observing

Since including libaio-devel into the requirements, building on my Debian system fails.

Describe how to reproduce the problem

1. git clone https://github.com/zfsonlinux/zfs
2. ./autogen.sh && ./configure
3. LC_TIME=C make deb
   (setting env var to circumvent "make deb" fails due to "error: bad date in %changelog #7825 with my limited know how ;))

Include any warning/errors/backtraces from the system logs

make deb run exits at this:

make[2]: Verzeichnis „/home/sam/zfsonlinux/src/git/zfs“ wird verlassen
Installing zfs-0.7.0-1527_g55972a672.src.rpm
error: Failed build dependencies:
	libaio-devel is needed by zfs-0.7.0-1527_g55972a672.x86_64

I removed the requirement from rpm/generic/zfs.spec.in and make deb succeeded, maybe the Debian package does not provide files at the expected places or some other distribution specific characteristics?

Please ask for any possible helpful information, I will be happy to provide it ASAP.

Kind regards,

Martin
