I ran into that at first, too.  In short:

        pacman mingw-w64-{i686,x86_64}-perl

fixed it for me.

The crucial output appears on the terminal only, with nothing useful in 
config.log.  It's a missing <sys/wait.h> which the perl5 CORE/perl.h is 
trying to access in the test compile performed by configure (log excerpt 
attached), lead by CORE/config.h which claims it should be available.

But there is not <sys/wait.h> among Min's headers --- there's one in 
MSys2.  That pointed me to the solution: you need to have _MinGW_ 
edition(s) of Perl installed, not just MSys2's own one, to build the XS 
stuff.
