#2269 Investigated how to handle simple macros with arguments and started the task of implementing it.

This task is to finish implementing the handling as described in #2269 of the macros of the form:

#define LAPACK_dgees LAPACK_GLOBAL(dgees,DGEES)
#define LAPACK_GLOBAL(lcname,UCNAME)  lcname##_

So we can find the proper names of the LAPACK symbols.
