Occasionally curl updates introduce errors in https verification.
Add an explicit test for this capability, activated by an undocumented
option that we can use in CI to specify a URL to test.

LLVM Flang's preprocessor output is always valid fixed form Fortran with
a fixed line length of 72. If an application tries to use fixed form
with a different line length, this will fail in the
post-preprocessing compilation step as they will pass a flag asking for
a different fixed line length.

To fix this we can pass -ffixed-line-length-72 to the post-preprocess
compilation stage. This will be ignored when the input is free form
Fortran, and force to a 72 line length when the input is fixed.
