gsl ships a program gsl-config, which very probably will give you the
necessary information. I would test for it with a combination of

AC_ARG_VAR(GSL_CONFIG, ...)
AC_PATH_PROGS(GSL_CONFIG, gsl-config, ...)

and then get the flags by running $(GSL_CONFIG) with the appropriate
options.

At least the Debian packages contains an M4 macro (gsl.m4) written by
the GNU Scientific Library project. Did you check it out? It maybe
already contains pre-defined tests, that offer the functionality you are
looking for.
