amit_at_expertsexchange,

You question is posed in very vague terms.

Can you take the time to fully state your question please?

They are not options. They are commands :

        nm : lists the symbols in an object file
        ld : is the linker - it links object files together (into an executable eg.)
        gcc : is the compiler - it compiles object files from source code

For more info, you can always do a man on it, for example :

        man nm

nm prints symbols in an executable, library or object  file
ld loads (links) object files to produce an executable or shared object
gcc is the GNU C compiler (gcc nowadays stands for Gnu Compiler Collection - it is a frontend for C++, FORTRAN and many others). The -Wall options instructs it to issue warnings for a number of common possible mistakes.
A Makefile can include these commands, but it can include *any* commands. These commands are in no way specific to make.
