GenerateExportHeader: use double quotes around _gcc_version 

The GenerateExportHeaders test was failing on one machine, the version
could not be determined there, so the _gcc_version was empty,
so the first argument to if() was empty, so it complained:
http://open.cdash.org/testDetails.php?test=135623436&build=2016288
Use double quotes to turn the non-existant first argument into an empty
string.
