GPRBuild does not find gprconfig when called from the Windows Subsystem for Linux

I have installed GNAT GPL 2017 on my Windows 10 system. Now I want to call the compiler from within a linux shell running on the Windows Subsystem for Linux. By adding the bin directory of my GNAT installation to the PATH, I got the following to work:

$ gnatmake.exe -P yaml.gpr

However, using GPRBuild does not work:

$ gprbuild.exe -P yaml.gpr
gprbuild: could not locate gprconfig for auto-configuration

I tried to call gprconfig from the command line and got this:

$ gprconfig.exe
No compilers found for target i686-pc-mingw32

It seems like gprbuild and gprconfig have problems with locating the GNAT binaries, while gnatmake is perfectly able to. How do I get gprbuild to work? Is there some environment variable I need to set?

I could build project using gprbuild on my Windows 10 / Ubuntu subsystem without any additional manipulations. I have gnat bin directory in Windows PATH and it looks like the same PATH uses in linux subsystem. It looks like gprconfig search compilers in PATH. You may try gprconfig.exe --mi-show-compilers to check if it found any of them.

Kind regards
