Use auditwheel to compute the platform tag

[mayeut]

libclang currently publishes a manylinux1 wheel however, it is not compatible with manylinux1. Use auditwheel to compute the correct platform tag.

Our goal is the compatibility with manylinux1 to make it as portable as possible. I would verify the detail later.

At the moment, here is the output of auditwheel:

[root@739578150fa1 ~]# auditwheel show ./wheels/libclang-14.0.1-py2.py3-none-manylinux1_x86_64.whl 

libclang-14.0.1-py2.py3-none-manylinux1_x86_64.whl is consistent with
the following platform tag: "manylinux_2_17_x86_64".

The wheel references external versioned symbols in these
system-provided shared libraries: libm.so.6 with versions
{'GLIBC_2.2.5'}, libz.so.1 with versions {'ZLIB_1.2.0'}, libc.so.6
with versions {'GLIBC_2.14', 'GLIBC_2.3.4', 'GLIBC_2.2.5',
'GLIBC_2.11', 'GLIBC_2.3', 'GLIBC_2.17', 'GLIBC_2.15', 'GLIBC_2.6',
'GLIBC_2.4'}, libpthread.so.0 with versions {'GLIBC_2.2.5'},
libdl.so.2 with versions {'GLIBC_2.2.5'}

This constrains the platform tag to "manylinux_2_17_x86_64". In order
to achieve a more compatible tag, you would need to recompile a new
wheel from source on a system with earlier versions of these
libraries, such as a recent manylinux image.

Hi @mayeut,

I have merged a pull request #31 to build the linux amd64 artifacts using the manylinux2010 container. The next release will be llvm v14.0.6 and will be delivered this weekend.
