[ptxdist] [PATCH] udev: standalone variant fails to build with newer toolchains

["Jürgen Beisert" <jbe@pengutronix.de>]

udev: standalone variant fails to build with newer toolchains
    
udev cannot be linked due to the use of the 'mq_getattr' call which requires
librt to link successfully.
    
The configure script already checks for "clock_gettime" in order to add librt
to the list of required libraries. This is valid only (according to the manual
page) for glibc version before 2.17. With the new glibc-2.18 in the 2013.12
toolchain librt isn't required anymore.
    
This patch adds a second test for 'mq_getattr' to force the librt for newer
glibc revisions as well.
