[Bug 1812084] Re: Build failure on RTEMS 4.10.2

[Andrew Johnson via Core-talk <core-talk at aps.anl.gov>]

That might not be true for 3.15 which is where Heinz is working; I only
build the RTEMS qemu target on my 7.0 branch, so I'm not sure.

I applied his latest patch to my 3.15 branch and my uC5282 target built
successfully. I then manually applied it to the 7.0 branch and it builds
successfully there too. Of course the change itself is in a routine that
is called from epicsThreadShow() so we don't have a test for it. I added
a call to the end of MAIN() in epicsThreadTest.cpp and it seemed to work
on the qemu target:

 0a010001   52 147/108     RUN          _main_

I'm happy to apply a version of this patch to 3.15, any objections?
