Using an old .config in combination with "make oldconfig" can cause an incorrect detection of the compat compiler: $ grep CROSS_COMPILE_COMPAT .config CONFIG_CROSS_COMPILE_COMPAT_VDSO="" $ make oldconfig && make arch/arm64/Makefile:58: gcc not found, check CROSS_COMPILE_COMPAT. Stop. Accordingly to the section 7.2 of the GNU Make manual "Syntax of Conditionals", "When the value results from complex expansions of variables and functions, expansions you would consider empty may actually contain whitespace characters and thus are not seen as empty. However, you can use the strip function to avoid interpreting whitespace as a non-empty value." Fix the issue adding strip to the CROSS_COMPILE_COMPAT string evaluation.
