Build fails when glibc 2.17 is used

[TZ86]

When I try build eudev with latest glibc, it fails on udevd linking:

  CCLD     udevd
./.libs/libudev-core.a(libudev_core_la-sd-daemon.o): In function `sd_is_mq':
sd-daemon.c:(.text+0x94a): undefined reference to `mq_getattr'
collect2: error: ld returned 1 exit status

I fixes it by adding -lrt flag to libudev_core_la target: http://pastebin.com/hLfGSy9i

Flameeyes already pointed why in his review, if it uses posix message
queues configure should check for them.

lu-zero: yes and no. If we needed mq_* we would have to check for it, but that code is now dead. It appears in sd_is_mq() in src/udev/sd-daemon.c which is no longer used. Commenting it out and the prototype in the header file leaves eudev building okay. Nor is the symbol exported, so we should be able to just comment it out.

Any comments before I do the hacking!

Actually AxS has convinced me pretty much all the code in sd-daemon.c is dead. We're just going to remove it all and test.

@ reporter, can you please test again. This should be fixed in master/HEAD.

Thanks for the report!

blueness: Yes, it works.

Thanks!
