 I'm testing RSB git source updated 2021-11-10 and it fails on freshly
 installed msys2/windows 10 platform with:
 ```
 karel at DESKTOP-755H9VE MINGW64 /c/r/rtems-source-builder/rtems
 $ ../source-builder/sb-check
 RTEMS Source Builder - Check, 6 (efa44e47a7d2 modified)
 Environment is ok

 karel at DESKTOP-755H9VE MINGW64 /c/r/rtems-source-builder/rtems
 $ ../source-builder/sb-set-builder --prefix=/c/r/rr 6/rtems-sparc
 RTEMS Source Builder - Set Builder, 6 (efa44e47a7d2 modified)
 Build Set: 6/rtems-sparc
 config: devel/dtc-1.6.0-1.cfg
 package: dtc-1.6.0-x86_64-w64-mingw32-1

 ```
 the problem report is attached.

 Joel adds: dtc does not build on msys2. It requires fnmatch.h which is not
 present. Alternative fixes include finding an alternative for fnmatch on
 msys2, providing an implementation to be used on msys2, or adding gnulib
 which is a portability package to our RSB packages on msys2.

 Also there may be other tickets for the same issue.
