Thanks for the test case. 

With cygwin 3.1.2, I confirmed make stops for a minute at:

.....
.....
echo running thread 98
echo running thread 99
running thread 98
cc    -c -o hang.o hang.c
running thread 99
MinGW/bin/gcc -MP -MM -MT test98.d -M -o test98.d test98.c && MinGW/bin/gcc -c -
o test98.o test98.c
MinGW/bin/gcc -MP -MM -MT test99.d -M -o test99.d test99.c && MinGW/bin/gcc -c -
o test99.o test99.c
cc    -c -o test.o test.c

and displays following after a minute.

cc   hang.o test00.d test01.d test02.d test03.d test04.d test05.d test06.d test07.d test08.d test09.d test10.d test11.d test12.d test13.d test14.d test15.d test16.d test17.d test18.d test19.d test20.d test21.d test22.d test23.d test24.d test25.d test26.d test27.d test28.d test29.d test30.d test31.d test32.d test33.d test34.d test35.d test36.d test37.d test38.d test39.d test40.d test41.d test42.d test43.d test44.d test45.d test46.d test47.d test48.d test49.d test50.d test51.d test52.d test53.d test54.d test55.d test56.d test57.d test58.d test59.d test60.d test61.d test62.d test63.d test64.d test65.d test66.d test67.d test68.d test69.d test70.d test71.d test72.d test73.d test74.d test75.d test76.d test77.d test78.d test79.d test80.d test81.d test82.d test83.d test84.d test85.d test86.d test87.d test88.d test89.d test90.d test91.d test92.d test93.d test94.d test95.d test96.d test97.d test98.d test99.d   -o hang

Is this the same as your problem?

If so, it goes without stopping 1 minute with patch:
https://cygwin.com/ml/cygwin-patches/2020-q1/msg00148.html

In any case, the following error occurs.

/usr/lib/gcc/x86_64-pc-cygwin/7.4.0/../../../../x86_64-pc-cygwin/bin/ld:test00.d: file format not recognized; treating as linker script

collect2: error: ld returned 1 exit status
make: *** [<builtin>: hang] Error 1
make: *** Waiting for unfinished jobs....

Is this as you expected?
