#182: Variable-assignment options to "make" gain additional whitespace

 Priority:  minor   |   Milestone:     
Component:  Cactus  |     Version:     
 Keywords:  make    |  
--------------------+-------------------------------------------------------
 If you build a Cactus configuration using

 make <configname>-config <option1>=<value1> <option2>=<value2>

 the <value1>... get spaces added to them in configs/<configname>/config-
 info.  This does not happen if you use options from a file.  Depending on
 how the variables are used, this extra space at the end can be a problem
 (e.g. it causes problems with GSL_DIR, as the GSL script doesn't expect
 whitespace at the end of the variable).

 I traced this to a greedy regular expression in setup_configuration.pl.
 The attached patch fixes the problem, but has not been tested extensively.
