dtc build failure on msys2 - all rtems6 target tools fail to build on Windows 10

[kgardas]

I'm testing RSB git source updated 2021-11-10 and it fails on freshly installed msys2/windows 10 platform with:
`

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.

dtc compilation failure problem report.

Adding SoC as a ticket because I think this is a possible small SoC project. Possible solutions include adding gnulib to the RSB bset for msys2 or modifying dtc to use other APIs for this functionality.
