Library layout

Hi,

I was trying to strip a MSVC static library generated by Rust. It failed with
the following error:

> strip -K gst_plugin_rswebrtc_register -K gst_plugin_rswebrtc_get_desc -o 
> xxx.lib ..\gstrswebrtc.lib
> D:\msys64\ucrt64\bin\strip.exe: illegal pathname found in archive member: 
> E:/cerbero/build/sources/msvc_x86_64/gst-plugins-rs-0.12.0-alpha.1/_builddir/x86_64-pc-windows-msvc/release/build/ring-13371a66ab60b364/out/poly1305_vec.obj

This error was introduced in the following commit:
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=dd9b91de2149ee81d47f708e7b0bbf57da10ad42
. I believe this check should not cover this particular case, since I'm not
unpacking the library itself.

(I cannot attach the library itself as it's 250MB -- a compressed 7z will be
linked after submission. I do have attached the output of nm for reference.)
