| |
Currently, this Makefile hardcodes GNU ar, meaning that if it is not available, there is no way to supply a different one and the build will fail.
$ make AR=llvm-ar CC=clang LD=ld.lld HOSTAR=llvm-ar HOSTCC=clang \ HOSTLD=ld.lld HOSTLDFLAGS=-fuse-ld=lld defconfig modules_prepare ... AR /out/tools/objtool/libsubcmd.a /bin/sh: 1: ar: not found ...
Follow the logic of HOST{CC,LD} and allow the user to specify a different ar tool via HOSTAR (which is used elsewhere in other tools/ Makefiles).
