add cif_api

[Crghilardi]

This PR adds a build_tarball.jl for cif_api.

This is what comes out of the wizard for me on a x86_64-mingw-* platform, *-linux-* still needs some tinkering but I wanted to see how the other platforms do as well.

Closes #2680

Ugh, looks like CPPFLAGS as environment variable doesn't work as expected? That's really weird

[Crghilardi]

Any ideas on why the cxx03 versions of everything are failing? I searched the repo for every keyword I could think of and it doesn't look like it requires some fixed standard?

My hunch is that it doesn't like GCC 4: when we don't specify the preferred GCC version, cxx03 uses GCC 4, cxx11 GCC 5. But I didn't try to build locally to see what's going on. To verify my hypothesis you can add preferred_gcc_version=v"5" to build_tarballs()

[Crghilardi]

Some of the cxx03 work now, but some of the platforms that were working are broken. It's like squeezing a balloon

EDIT: was just missing a dollar sign lol

Digging into the config.log for i686-linux-* I saw a number of undefined reference issues such as:

configure:13419: result: no
configure:13426: trying again with -licuio -licuio -licui18n -L/workspace/destdir/lib -licuuc -licudata
configure:13430: checking for u_fopen_69

collect2: error: ld returned 1 exit status
configure:13430: $? = 1
configure: failed program was:

It sounds like __divmoddi4 was added in GCC 7, and is only used in i686?

[giordano]

Can you try building with GCC 7? The weird thing is that HarfBuzz_ICU was built with GCC 5:

Yggdrasil/H/HarfBuzz/common.jl

Line 83 in d923580

build_tarballs(ARGS, name, version, sources, script, platforms, products, dependencies; preferred_gcc_version=v"5", julia_compat="1.6")

[Crghilardi]

Bumping gcc did fix it for i686-linux-*, see latest commit f1b3f1d.

The remaining *-minGW-* failures seem to all be on the custom install scripts. I don't have a solution for that yet, still thinking

[giordano]

"Good" news: rebuilding HarfBuzz_ICU for i686-linux-gnu with GCC 5 doesn't work anymore. Why knows how it worked before 😕 Well, I'm going to merge this now

Edit: ugh, no, I was checking out an old version of BinaryBuilderBase. So now I'm back to "how HarfBuzz_ICU works?!?!"
