libpsl is a lib that provides the Public Suffix List: the list
of all TLDs.
It's an optional feature of libcurl that we dont need for libkiwix.
Leaving it included causes issues when compiling for apple_all_static
on x86_64 as libpsf is installed (and thus found by libcurl's configure)
but is obviously only for x86_64.
An alternative could be to either cross-compile it first and properly
reference that version.
That sounds like too much effort for a feature we know we dont need.

It mainly allow to run command in directory containing space.
(Hello, `C:\Program Files\...`)
It would also allow to work on directory containning spaces
(`C:\Users\John Doe`) but xapian configure (at least) expressly doesn't
support it :/
- Run the command without shell=True
- The command must be a list instead of a string.
- All options must also be a list (or an iterable).
On ubuntu, the libcurl package is compiled with libkrb (kerberos).
However, no libkrb5.a is provided and so, we cannot link statically.
As we are not using kerberos, we can (and must) compile ourselves libcurl.
