Values written to rbconfig.rb by mkconfig.rb aren't properly quoted.
On solaris, the variable ECHO_C will be added to rbconfig.rb with the
value "\c", which in unparsable by Ruby (becomes control + "). This patch
to mkconfig.rb should fix it:

     if fast[name]

I sense the need for a generic way to write objects in a ruby parseable
way? String#inspect could have been used in this case, but it does not
guarantee that parsing the output will result in an equivalent object.
