There are two solutions, you can specify a preferred compiler in a
recipe or change the main compiler.
To change preferred compiler in a recipe:
TOOLCHAIN_pn-<recipe-name> = "<your_compiler>"
DEPENDS_append_pn-<recipe-name> = " <your_compiler>-cross "
To change the main compiler:
TOOLCHAIN = "<your_compiler>"
There is a example in the official wiki :
