Function findObjdump

internal/binutils/binutils.go:163–184

findObjdump finds and returns path to preferred objdump binary. Order of preference is: llvm-objdump, objdump. On MacOS only, also looks for gobjdump with least preference. Accepts a list of paths and returns: a string with path to the preferred objdump binary if found, or an empty string if not fou

(paths []string)

// a boolean if any acceptable objdump was found;
// a boolean indicating if it is an LLVM objdump.
