PATCH 1/1 pkg-config: allow kernel to be build with esdk

When the kernel's menuconfig target is called while using the esdk or an esdk-based container, the pkg-config info that is found is not correct. The pkg-config info is for the target, but we need the eSDK's information in order to build the host based menuconfig.

The new pkg-config script checks both that it's in SDK and being called from the check-lxdialog script in order to limit the scope of when the pkg-config automagically switches to pkg-config-native.

This script also replaces the default pkg-config-native script.

Ping on this patch?

It has been tested with a variety of shells (sh, bash, dash, ash).  Is there any further concerns?

Sau!

To be honest, I'm scared of adding this kind of complexity to the system. I appreciate the problem you're trying to solve but I worry adding this kind of change is complex, invasive and introduces too much risk.

I have some specific worries with this implementation too, in particular that it changes on target pkg-config, it really should only change nativesdk-pkgconfig? If we have risk, we want to minimise that risk and adding this wrapper everywhere doesn't seem to do that...

Cheers,

Richard

There is no nativesdk-pkgconfig, but I had some confusion around the pkg-config-native and it's usage of a pkg-config binary.  I was getting some recursion initially and my feeble brain thought it was the target version :-(.

I have rebuilt this patch and will send a V2 that ONLY affects the pkg- config-native, basically expands the script to check if it's being called as -native or from the Kernel's check-lxdialog.

I am also going to change the script such that it checks it's base name of pkg-config and only then add the parent pid name checking.

I hope that will mitigate the risk.
