On linux redhat, using GNU makefile, is it possible to read the
argument of a make command, for example:


make hello

Is there a programmable way to read the argument hello?

Not in the way you are probably expecting. Make processes arguments
into "goals" (build targets).

See 'info make':
\\
`Make' will set the special variable `MAKECMDGOALS' to the list of
goals you specified on the command line.  If no goals were given on the
command line, this variable is empty.  Note that this variable should
be used only in special circumstances.

It's trivial to write a shell script, say ~/bin/make, to do this
for you. Ignoring quote errors, something like
#!/bin/sh
target=$1 /usr/bin/make $*

Don't say anything. Especially you.
