M2H_RCFILE envariable is not working

Hello,

During the testing of MHonArc2.4.8, I found that the envariable
M2H_RCFILE is not working.  However, the command line option
"-rcfile" is working ok.  Interested in the bug, I debugged some
files, and found that lib/mhopt.pl is responsible.

I am appending the one line patch which will correct the bug.
