I looked back through the commit history for Meson and there were a 
number of changes to the way that import libraries are handled between 
0.47.1 and 0.54.0.  I installed the meson releases in order, but was 
unable to build successfully with anything before 0.54.0 - I was seeing 
complaints about unknown linker flags building with Clang 11.0.0 and 
Link 14.27.29112.0 from Visual Studio 2019.

Assuming that builds with meson 0.47.1 and Clang/Link do work, I took 
the conservative approach of only making the change for the version of 
Meson where I know that /implib is handled correctly, leaving the 
previous behaviour unchanged for earlier versions which I'm unable to 
verify.
