[ELDK] Please update ELDK 5.5.x to 5.5.2

[Marek Vasut]

Hello all,

I am getting reports about occasional kernel crashes on ARMv7 [3]. I found out 
this is caused by GCC bug [1], resolved in Yocto 1.5.2 [2] and thus ELDK 5.5.2 . 
The git commit ID in Yocto and ELDK is 97c9163d97911dad0afcd0dae39e5c426e27e921 
. To prevent being affected by this bug, please update your ELDK 5.5.x to ELDK 
5.5.2 or newer.

[3] This is the backtrace caused by the bug. Please note that the PC is pointing 
to 'find_get_entry' function, which is miscompiled by the GCC 4.8.x without the 
patch:
