The log does have the error, and I get it when building by hand too:

Hmmm.. that's weird. You should never get a truncation error linking
minimum.exe.
It should always fit within the BSP's memory and not have any issues with
branches
or calls needing fixup.
Unless the wrong type of branch/jump/call instruction is used at start.S:86, I
have
no idea.If it's a form that assumes a short distance to the destination but is
going
to a symbol outside start.S and thus could be further.
Also, 6 of the samples such as hello.exe link without error.
The rv32imafdc BSP variant does not have CPU_CFLAGS.
rv32imafd links fine and has specific CPU_CFLAGS, rv32imafdc does not
have the flags.
(I'll research the gcc defaults and architecture differences next..)
I get a similar error on the frdme310arty BSP but only on a specific
POSIX testsuite executable:
start.o: in function `.L0 ':
/home/alan/rtems/test-build/rtems-tmp/build/riscv/frdme310arty/../../../bsps/riscv/shared/start/start.S:86:(.bsp_start_text+0x28):

My off hand guess is that this is a tool chain issue on certain host
systems. For example, I never got this error on our OpenSUSE machines.
