Mask non-reproducible linker artifacts in libs #2661

@riverar riverar commented Sep 18, 2023

The Microsoft Visual C++ (MSVC) linker (as of 14.37.32822.0) does not create reproducible import libs. It supports a /Brepro flag to stabilize archive member header timestamps but misses other elements, such as import header time/date stamps, coff file header time/date stamps, and the compiler version symbols emitted by itself into the COFF symbol table.

The tool_msvc crate has been updated to take advantage of the /Brepro flag and mask additional non-reproducible elements, including S_COMPILE2_ST symbols in the .debug$S symbol section. (See also: link!CImplib::EmitNullImportDescriptor)
