We can build our kernel and uboot fine but when we try to build a more complex image with qt5 we have not succeeded any build since yesterday.

I hit this issue w/ Aarch64 builds, and the issue was that gcc linker definition 
did not match the installed library path definition.

In the aarch64 case, the ld.so lives in '/lib', and everything else in the 'oe 
libdir' (which if set to 'lib64') was causing issue.  I finally fixed it in my 
local build by symlinking ld.so into both places.

(I realize this isn't likely on the same architecture, but I suspect the same 
issue is possible here.  Basically the compiler and glibc are not synchronized 
and are looking in different locations for their components.)

I don't use rm_work myself.  But a few of my coworkers do.  The only place 
they've hit an issue is on a specific CentOS based machine.  We've not been able 
to track it down, but rm_work appeared to run BEFORE the final staging...

There was a recent bug found that affect systems with 64-bit inodes.  Check if 
you have that, you may need a 'pseudo' update... back porting from master should 
be fine for older versions.  (Master was updated yesterday?)
