This is not supposed to happen. I don't see this on my system.
There's some factor at work here that I cannot figure out: the
configure-time test for clock_gettime doesn't try to look for that
function in the pthreads library, it only tries the "normal" link
without any extra libraries, and if that fails, tries 2 extra
libraries: librt and libposix4, none of which I'd expect to see on
MS-Windows in a MinGW installation.
It could be something peculiar to MinGW64/MSYS2 build. Are you sure
libwinpthread dependency is not a requirement of the MinGW64 GCC port?
So please look in config.log, and tell how did pthreads get into this
test.

57 DLLs sounds excessive. I counted the ones I think Emacs uses on my
system, and only got as far as 32. Can you show a list of those 57
libraries?
