Hello Michael,

Thanks for the new release !


I had two small problems while upgrading to the latest versions:

- The toochain arm-cortexa8-linux-gnueabihf creates the directory 
gcc-4.8.2-glibc-2.18-binutils-2.24-kernel-3.12-sanitized but gcc's 
version
     reports 4.8.3 and ptxdist complains about the version mismatch. As a 
workaround I created a symlink 
gcc-4.8.3-glibc-2.18-binutils-2.24-kernel-3.12-sanitized which made 
ptxdist happy.

- udev 182 does not build with glibc 2.18 of the new toolchain:

     src/udevd-sd-daemon.o: In function `sd_is_mq':
     .../build-target/udev-182/src/sd-daemon.c:394: undefined reference 
to `mq_getattr'
     I found a patch which worked for me: (the failing code is dead code, 
which can be commented out ...)

     https://github.com/gentoo/eudev/issues/41
     
https://github.com/gentoo/eudev/commit/3d6f228db94e8bfb81f3b163739250e9a578e819


The resulting code runs fine on our iMX.537.


Best regards,

Matthias
