The recipe passed OBJTOOL, ARCH and CROSS_COMPILE explicitly, but not CC or the binutils. Makefile-assigned values (e.g. from LLVM=1) are not visible in the recipe environment unless forwarded: $ LLVM=1 make -C tools/objtool tests ... # preflight # compiler gcc (GCC) ... Pass CC, LD, READELF and OBJCOPY the same way as ARCH and CROSS_COMPILE, so fixtures are built and inspected with the toolchain make selected: $ LLVM=1 make -C tools/objtool tests ... # preflight # compiler clang version 21.1.8 ...
