This has failures of required windows machines.

Yup:

+ cd /d/a/1/s/src
+ /d/a/1/s/tools/dmd2/windows/bin/make.exe -f win32.mak reldmd-asserts DMD=/d/a/1/s/generated/windows/release/32/dmd
.azure-pipelines/windows.sh: line 82: /d/a/1/s/tools/dmd2/windows/bin/make.exe: No such file or directory

Same failure for druntime. It's because we no longer ship make in the releases.

Tentative fix: #11794 (stable first, then to be included here)
