Don't run "set -o igncr" before configuring libffi

It used to make the build work on cygwin, but now it breaks it instead:
    config.status: creating include/Makefile
    gawk: ./confLqjohp/subs.awk:1: BEGIN {\r
    gawk: ./confLqjohp/subs.awk:1: ^ backslash not last character on line
    config.status: error: could not create include/Makefile
    make[2]: *** [libffi/stamp.ffi.configure-shared] Error 1
    make[1]: *** [all] Error 2
