compiling package with bitbake with CROSS_COMPILE flag

Hi

I hope I am asking this question to the right mailing list, since it is related to meta modules classes.

I have a package trying to compile using bitbake.

When you inherit module, I think CROSS_COMPILE option is enabled by module-base.bbclass.

I get below error because of this CROSS_COMPILE flag.

error: inlining failed in call to always_inline 'icp_adf_pollQueue': function body not available

I disabled the flag in my recipe by export CROSS_COMPILE="".
Then it compiled fine.

My question is
what this CROSS_COMPILE flag  does when bitbake runs?  Does it set any extra compiler flags, which is not accepted by my package I am building using bitbake?
How do you avoid this inlining issue when CROSS_COMPILE flag is enabled?

Thanks
Kishore.

CROSS_COMPILE is set in order for the kernel module makefiles to be able to 
determine the correct prefix for the compilation tools. If it isn't set I think 
you would potentially be using the wrong compiler and tools for the target 
platform.
