Ah ok, yes you have followed the documentation.

You are building the development version of RTEMS and not the 4.11 
branch. The documentation was written before I made the 4.11 releases 
and it needs updating. I am sorry for this.

For git you need to:

  $ git checkout 4.11

Also see below for a tar file of the source to build rather than using git.

This is what I am asking. Your RSB command should have built RTEMS for 
you. The RSB builds the kernel when released. I have not updated the 
documentation discuss this.

The source for the kernel you can use is:

 
https://ftp.rtems.org/pub/rtems/releases/4.11/rc/4.11.2-rc4/rtems-4.11.2-rc4.tar.xz

Please download and untar the file to a directory and then run the 
configure command:

  $ cd /c/opt/rtems
  $ tar Jxf rtems-4.11.2-rc4.tar.xz
  $ mkdir erc32
  $ cd erc32
  $ /c/opt/rtems/rtems-4.11.2-rc4/rtems/configure \
      --prefix=/c/opt/rtems/r4.11.2 \
      --target=sparc-rtems4.11 \
      --enable-rtemsbsp=erc32 \
      --enable-posix

Please note there is no need to bootstrap the source. The release are 
bundled with the needed files.

Yes. This is correct, you just need to use the correct source.

Again thank you for the reports and helping us see the issue. I have 
created ticket #2998 to record this issue.
