From: Bruce Ashfield <[email protected]>
When building a module on target, we use the native compiler
(always "gcc") versus the same compiler, but named in a cross
compiler manner, for the kernel build.
The kernel captures the compiler string in several places,
some of which we are already fixing, but others we are not
(as they don't cause issues).
But when building an on target module, the main kernel Makefile
compares compiler strings and outputs a warning similar to:
warning: the compiler differs from the one used to build the kernel
The kernel was built by: x86_64-poky-linux-gcc (GCC) 11.3.0
You are using: gcc (GCC) 11.3.0
We drop the cross compilation prefix from the captured compiler
string, and we avoid the warning.
RP: tweaked one sed expression to fix quoting issue with 5.15
