The tests target already passes ARCH and CROSS_COMPILE into
run-tests.sh. lib.sh uses those to pick a default compiler and
binutils:
CC=${CC:-${CROSS_COMPILE}gcc}
LD=${LD:-${CROSS_COMPILE}ld}
READELF=${READELF:-${CROSS_COMPILE}readelf}
OBJCOPY=${OBJCOPY:-${CROSS_COMPILE}objcopy}
Those defaults only apply when the variables reach the shell that sources
lib.sh. 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 ...
