source: configure @ ddb3c08

Last change on this file since ddb3c08 was 21f450c, checked in by dequis <dx@…>, at 2016-05-26T00:15:15Z

configure: add 'arch' variable again, needed for portability

It was removed by 2e78f75, but it only needed to remove the variable
that was written to config.h, not the one that was used internally by
configure.

Property mode set to 100755
